with rectal cancer // need to determine exact\nstaging and depth of rectal mass invasion preoperatively and to plan for XRT\n\nTECHNIQUE: Multiplanar MRI of the pelvis is obtained at 1.5 Tesla per the\nrectal mass protocol. T1 and T2 weighted sequences are acquired both pre and\npost administration of 8 mL of gadavist. 1 mg of intramuscular glucagon was\nadministered to decreased bowel peristalsis.\n\nCOMPARISON: MRI of the pelvis dating ___. Also CT abdomen pelvis\ndating ___.\n\nFINDINGS: \n\nAs was seen on the prior examination, there is a large mass replacing the\nmajority of the anus. Total anterior to posterior extent of tumor now measures\n6.5 cm, increased from prior 5.4 cm. The mass is predominantly T2\nhyperintense with restricted diffusion (6:74). Peripheral enhancement is\npresent (200:28). Anteriorly and on the left, this replaces the internal\nsphincter, while posteriorly and on the right, the mass involves both internal\nand external sphincter, with extension posteriorly and to the ischial anal\nfossa and subcutaneous tissues of the right buttock. The tumor now extends\nfurther posteriorly to the skin surface (08:22). The degree of anal sphincter\ninvolvement classifies the rectal tumor as T3.\n\nThere is also abnormality of the distal rectum, predominantly the posterior\nwall, which is thickened and hyperenhancing. Unlike the anal component, this\nwall thickening is T2 hypointense (09:14). Based on mucinous adenocarcinoma\npathology, this distal rectal abnormality likely represents the site of tumor\norigin with inferior extension and mucinous differentiation. There is\nirregularity of the left posterior lateral distal rectal wall with abnormal\nenhancement extending posteriorly to the levator ani muscle and mesorectal\nfascia (200:55), although consistent with T3 tumor stage. While this abuts\nthe muscle, there is no definitive involvement. Anterior to the left aspect of\nthe distal rectum there is also adjacent irregularity, as previously\ndescribed. The appearance is stable as compared to prior.\n\nSmall perirectal nodes are present on the right (200:61, 71, 77). None\nmeasure greater than 4 mm, therefore do not have imaging appearance of\nmalignant involvement. Pelvic sidewall nodes are also identified, left\ngreater than right. These are neither pathologically enlarged, nor\ndemonstrate heterogeneous enhancement to suggest tumor involvement. Inguinal\nnodes are slightly asymmetric, left larger than right, but also are not\npathologically enlarged and do not demonstrate concerning enhancement\n(200:55). No definitively pathologic nodes are identified within the pelvis.\n\nThere is no tumor invasion of the vagina or bladder.\n\nThere is diffuse subcutaneous as third spacing of fluid (8: 25). There are\nsmall bilateral hip joint effusions and a synovial hyperenhancement. No\nconcerning osseous lesion is appreciated.\n\nThe patient is status post hysterectomy. There is re- demonstration of focus\nof T1 hyperintense, nonenhancing material at the left aspect of the vaginal\ncuff, likely representing residual proteinaceous or hemorrhagic material. The\nvagina, urinary bladder and urethra are unremarkable.\n\nTumor: semi annular (predominantly posterior and left lateral within the\ndistal rectum and circumferential, right greater than left within the anus)\nDistance from anal verge (AV) (mm): 0\nExtends cranio-caudally (CC) (mm): 82\nDistal edge lies: 35 mm below puborectalis sling\nUpper border lies: Not well seen\n\nSTAGING\nInvading tumor edge: From 2 o'clock to 6 o'clock\nMuscularis propria: extends through\nExtramural spread (mm): 8\nExtramural venous invasion (EMVI): no\nPeritoneal reflection: not involved\nAdjacent pelvic organs (Levator ani, prostate, vagina): Abnormal signal and\nenhancement extends to left posterior levator ani muscle, without definitive\ninvolvement\n\nFOR DISTAL RECTAL TUMORS AT/BELOW LEVATOR ORIGIN\nIntersphincteric plane: invaded\nExternal anal sphincter: Invaded on the left\nIschiorectal fossa: Invaded on the left\n\nClosest CRM (Circumferential resection margin) at: 5 o'clock by tumor\nClosest CRM to MRF (Mesorectal fascia) (mm): 0 Streaky enhancement extends\nfrom left posterior rectum to levator ani muscle and distal most MRF.\nClosest CRM to AV (anal verge) (mm):\n\nMesorectal lymph nodes: None\nPelvic side wall nodes: no\n\nStaging Assessment: mrT3c\nExtramural spread (mm): >8\nCRM: involved\nEMVI: negative\nLocation: low rectal tumor with anal extension\nNodal: N0\nMetastasis: M0\n\nIMPRESSION: \n\nInterval growth of the previously demonstrated distal rectal tumor, with\ninferior anal extension and mucinous differentiation, now extending further\nbeyond of the right posterior external anal sphincter and into the\nsubcutaneous tissues of the right buttock. The rectal tumor extends beyond\nthe muscularis propria into the mesorectal fat posteriorly on the left,\nabutting the levator ani muscle and mesorectal fascia without obvious\ninvolvement.

adenocarcinoma. Evaluate mass. New diagnosis.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted images of the pelvis were acquired\non a 3 Tesla magnet including dynamic 3D imaging prior to, during and after IV\nadministration of 0.1 mmol/kg of gadolinium-DTPA. Patient was injected with 1\nmg of glucagon intramuscularly prior to the scan. Multiplanar 2D and 3D\nreformations and subtraction images were generated on an independent\nworkstation.\n\nFINDINGS: There is a polypoid rectal mass primarily involving the right wall\nof the rectum. The mass extends inferiorly to the puborectalis muscle and\ninvolves the superior aspect of the internal anal sphincter on the right. The\nmass is 3 cm in length. The tumor involves the muscularis propria in the\nright side of the rectum wall. In addition at the ___ o'clock position there\nis a soft tissue component that extends through the muscularis propria. These\nfindings are compatible with MR stage T3 tumor. The tumor is 3-4 mm from the\nright anterior mesorectal fascia. Inferior to the mass there is moderate\nenhancement anteriorly and to the right which may be due to inflammation,\nulceration or post-biopsy changes.\n\nThere are several perirectal nodes measuring up to 9 mm. There are also up to\n7-mm nodes seen anterior to S2 along the superior rectal artery. These nodes\ndemonstrate enhancement, a few have minimal central hypointensity suggestive\nof necrosis on the post-contrast images. The largest node is 4-5 mm from the\nright lateral mesorectal fascia. Overall findings are suggestive of N2\ndisease.\n\nMultiplanar 2D and 3D reformations delineated the dynamic series with multiple\nperspectives.\n\nIMPRESSION:\nDistal rectal mass extending into perirectal fat right anterorlaterally with\ninferior extension that appears to be into the superior internal anal\nsphincter on the right. Circumferential resection margin is 3-4 mm. There are\n4 suspicious perirectal nodes up to 9 mm.\n\nOverall MRI findings are compatible with stage T3N2 disease.\n\n\n", "rows": [ { "field": "Age", "GPT 5.5 Output": "not mentioned", "GPT Output,

PET dated ___. \n\nFINDINGS:\n\nThere is a mass within the lower rectum which is abutting the anorectal\njunction and extends from the 12 o'clock to 7 o'clock position on the left\nside. It measures 2.9 cm in diameter (sequence 100 image 38). It has\ndecreased in size since the previous MRI and is 3.6 cm from the skin of the\nanus. \n\nThe mesorectal nodes have decreased in size since previous. The node to the\nright of the rectum which measures 0.7 cm in short-axis diameter (previously 1\ncm) demonstrates heterogenous enhancement post-contrast (sequence 200 image\n62) and was hot on the recent PET, consistent with metastatic involvement. It\nlies 3 mm from the mesorectal fascia. The node to the left of the rectum\nwhich is lying on the mesorectal fascia measuring 0.7 cm in diameter\n(previously 1.4 cm) is of low signal on T2 (sequence 9 image 34) and does not\ndemonstrate significant enhancement . This did not take up FDG on the recent\nPET and likely represents a completely fibrosed node post-treatment. A 0.4 cm\nnode is also identified to the left of the rectum (sequence 9 image 33) and\nhas also decreased in size (previously 0.7 cm). The 0.9 cm node to the left\nof the rectum on the previous MRI (sequence 5b image 40 on the previous study)\nnow measures 0.2 cm (sequence 9 image 28). \n\nSigmoid diverticulosis is again noted. The bladder is within normal limits.\nThe uterus and ovaries are unremarkable. \n\nThere is cortical thickening and coarsening of trabeculae involving the right\nilium which appears consistent with Paget's disease. There are degenerative\nchanges on either side of the right sacroiliac joint. There is also sclerosis\non the iliac side of the left SI joint which likely represents osteitis\ncondensans ilii. No destructive osseous lesions. \n\nIMPRESSION:\n1. Decreased size of low rectal tumor within 1 cm of the anorectal junction\nand decreased size of mesorectal nodes. The findings are most compatible with\nT2N1 rectal cancer. \n\n2. Sigmoid diverticulosis. \n\n3. Paget's disease involving the right ilium with right SI joint degenerative\nchange. Osteitis condensans ilii involving the iliac side of the left SI\njoint. \n\n\n", "rows": [ { "field": "Age", "GPT 5.5 Output": "not mentioned", "GPT Output, modified by Annotator Radiologist where

The mass extends\n5.9 cm in craniocaudal dimension. Its lowest margin is approximately 10 cm\nfrom the anal verge. It causes circumferential thickening and luminal\nnarrowing throughout its length. The lesion breaches the muscularis between\n___ o'clock on the right and extends for approximately 1.6 cm into the\nperirectal fat. There is significant amount of desmoplastic reaction as well\nas multiple abnormal-looking vessels surrounding the lesion, most probably\nharboring intravascular tumor.\n\nAnteriorly, between the posterior vaginal fornix and the anterior aspect of\nthe mass (8:20), there is a 1.6 x 2.5 cm relatively well-defined mass with\nsignal intensity similar to the primary tumor.

IM.\n\nCOMPARISON: CT available from ___.\n\nMRI OF THE PELVIS WITH AND WITHOUT IV CONTRAST:\n\nAn ill-defined eccentric sigmoid mass extends at least 6.2 cm in length\n(series 3 image 19), centered approximately 15 cm above the anal verge.

Concerning for recurrence. \nEvaluate for recurrence of rectosigmoid cancer.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted images were acquired on a 3 Tesla\nmagnet including dynamic 3D imaging obtained prior to, during, and after the\nuneventful intravenous administration of 10 mL of Gadovist. The patient also\nreceived rectal contrast, which consisted of a 16:1 mixture of barium and\nGastroMARK, and 1 mg of glucagon IM.\n\nFINDINGS: There is a large mass within the rectum at approximately 7 cm. \nThis involves the anastomosis at the previous lower anterior resection site. \nAt the anastomosis, there is extensive spiculation extending into the\nperirectal and presacral fat. This extends up to the sacrum, but does not\nappear to involve it. The left ureter extends into the spiculated mass\n(sequence 5, image 14). The left ureter proximal to this point is dilated\nmeasuring up to 0.7 cm in diameter.

There\nare also abnormal lymph nodes within the mesorectal fat measuring up to 0.5 cm\nin short axis diameter (sequence 1002, image 62).\n\nThe bladder is within normal limits. There is enlargement of the median lobe\nof the prostate gland with protrusion into the bladder, consistent with benign\nprostatic hyperplasia. An ileostomy is noted within the left iliac fossa. \nThere is diffuse red marrow reconversion within the lower lumbar spine and\nsacrum, which is likely secondary to anemia. No destructive osseous lesions.\n\nIMPRESSION: \n\nLarge recurrent tumor at the LAR anastomosis within the upper rectum, with\nextension into the perirectal and presacral fat.

Initial\nstaging.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted images were acquired on a 3 Tesla\nmagnet including dynamic 3D imaging obtained prior to, during, and after the\nuneventful intravenous administration of 18 mL magnevist. In addition, a\nmixture of dilute GastroMark and barium was administered as rectal contrast.\n\nMultiplanar reformations and subtraction images were generated on an\nindependent workstation.\n\nCOMPARISON: Correlation is made with torso CT ___.\n\nFINDINGS: There is a rectal mass, the inferior margin of which appears to be\napproximately 3.5 cm from the anal verge. The mass extends proximally for at\nleast 6 cm, to the level of the seminal vesicles. Inferiorly, the mass\nappears circumferential, however, its superior aspect appears to be\npredominantly anterior in location. Along its inferior aspect, there are\nlobulations of the contour along the outer surface, which appears to extend to\nthe mesorectal fat. These are appreciated both on T2W images (3:27) and\npostcontrast images (100:83). CRM is only 1-2mm at this level. \n\nInferiorly, the rectal wall appears to abut the prostate on the T2-weighted\nsequence. On the post-contrast images, however, the involved portion of this\nportion of the rectum appears more towards the mucosal surface. It is\nuncertain whether or not the serosal surface of the rectum at its interface\nwith the prostate is involved by tumor.\n\nOn the right, there is a concerning lymph node measuring approximately 5 x 6\nmm. This is best appreciated on series 100, image 71. On the left, there are\nlymph nodes that appear superior to the level of the tumor. The largest\nmeasures approximately 10 x 7 mm (series 100, image 28). An additional node\n(series 100, image 34) measures approximately 3 mm in greatest diameter.\n\nNote is also made of a 6 mm polypoid enhancing lesion at the 4:00 location of\nthe rectum, approximately 10 cm from the anal verge (200:67).\n\nThere is a T2 hyperintense structure at the level of S2, which may represent a\nTarlov cyst.\n\nVisualized bone marrow signal is within normal limits.\n\nMultiplanar 2D and 3D reformations provided multiple perspectives for the\ndynamic series.\n\nIMPRESSION:\n\n1) Dominant rectal mass extends approximately 6 cm from the level of the\nseminal vesicles (superiorly) to approximately 3.5 cm from the anal verge\n(inferiorly). At its inferior aspect, it appears circumferential, with\nthickness up to 1.2 cm, and superiorly, it involves the anterior rectum, up to\n2 cm in thickness. There are lobulated external contours of the lesion in its\nright mid portion, suggesting involvement extending into the mesorectal fat,\nconsistent with T3 disease by MR staging. CRM is around 1-2 mm as described. \nAnteriorly and inferiorly, the rectal wall appears to abut the prostate based\non the T2-weighted sequences. However, on the T1- weighted sequences, the\ninvolved area of rectum appears to involve mostly the mucosal surface. \nTherefore, it is difficult to ascertain whether tumor involvement extends into\nthe posterior margin of the prostate. \n\n2) Enhancing 6mm polypoid lesion at the 4:00 location, 10 cm from the anal\nverge as decribed. \n\n3) There is a concerning 6mm lymph node on the right side, inferiorly, in the\nregion of the tumor. Additionally, on the left, there are a couple prominent\nlymph nodes which appear superior to the tumor.

The mass is decreased in thickness in\nthe mid rectum but fairly similar in the lower rectum. In the mid rectum\nthere is decreased T2 signal intensity indicating fibrosis, however abnormal\nsignal remains in the lower rectum and distal mid rectum indicating residual\nintramural tumor.. Evaluation for residual diffusion signal abnormality is\nnot possible because of significant artifact from left hip arthroplasty. \nThere is no definite involvement of the internal sphincter.\n\nA left lower quadrant diverting ostomy is again seen.\n\nThere has been interval decrease in extent of the T2 hyperintense signal\nintensity in the previously expanded perirectal fat with now predominantly\nlinear bands of hypointense signal intensity on T2 weighted images with\nprogressive increased enhancement, likely due to fibrosis of lymphangitic\nspread of tumor. Again there are no discrete lymph nodes within the\nperirectal fat.\n\nUTERUS AND ADNEXA: The uterus is anteverted and measures 4.8 x 2.7 x 2.6 cm. \nThere are multiple uterine fibroids with a 8 mm T2 hypointense fibroid at the\nfundus which has a submucosal component, and a 1.7 cm cervical fibroid.

anteverted and measures 3.4 x 5.9 x 9.2 cm. Multiple sub\nserosal and intramural fibroids, the largest measuring 4.3 x 6.0 cm\nexophytically arising from the left uterine fundus.\nThe endometrium is normal in thickness for age and measures 2 mm.\nThe junctional zone is not thickened. Nabothian cysts are noted within the\ncervix.\n\nThe right ovary is visualized and appears within normal limits.\nThe left ovary is visualized and appears within normal limits.\n\nNo free fluid within the pelvis.\n\nLYMPH NODES: Several small IMV chain lymph nodes are noted measuring up to 7\nmm in short axis (axial series 8, image 107 and 108).\n\nBLADDER AND DISTAL URETERS: Normal contour of the urinary bladder wall. No\ndistal hydroureter.\n\nRECTUM AND INTRAPELVIC BOWEL: Evaluation of the intrapelvic bowel loops is\nlimited by motion artifact.\n\nThere is an endoscopic clip at site of prior endoscopic polypectomy, with\nassociated susceptibility artifact which limits evaluation of the rectum at\nthis site.

administration of 6 mL of Gadavist. 1 mg of\nintramuscular glucagon was administered to reduce bowel motion.\n\nFINDINGS: Approximately 6 cm from the anal verge is a nearly circumferential\nT2 hypointense, hypoenhancing mass involving a 5 cm length of the middle third\nof the rectum (3:18). The mass appears to involves the muscularis propria,\nwithout definite extension into the perirectal fat. Multiple spiculated T2\nhypointense enhancing spiculations radiating into the perirectal fat (6:17)\nlikely represent desmoplastic reaction. The circumferential resection margin\nis preserved, with a focal area of narrowing along the anterior margin, where\nthe tumor is separated from the posterior uterine wall (6:20) by a 3 mm\ndistance (due to paucity of perirectal fat in this region). The inferior\nmargin of the mass extends to a centimeter above the anal sphincter complex. \nMultiple enlarged perirectal lymph nodes are seen in the following images: an\n8 mm (902:25), 7 mm (902:30), 7 mm (902:35) and 5 mm (902:18) nodes. Few\nadditional sub-5-mm lymph nodes are seen in the perirectal region. A single\nenlarged lymph node measuring 8 mm (902:10) is seen along the internal iliac\nchain (902:10). \n\nThe sigmoid colon and imaged pelvic loops of small bowel are normal. \n\nA thickened endometrial cavity measuring 12 mm is seen, with focal T2\nhypointense enhancing material along the uterine fundus, (901:24). \n\nA 2 cm simple cyst is seen in the right ovary. The left adnexa appear\nunremarkable. \n\nThe urinary bladder is partially distended and appears unremarkable. \n\nThere is no pelvic free fluid. No marrow signal abnormality is evident. \n\nIMPRESSION:\n\n1. A nearly circumferential tumor involving a 5 cm segment of the mid rectum,\napproximately 7 cm from the anal verge.

obtained prior to,\nduring, and after the uneventful intravenous administration of 0.1 mmol/kg of\ngadolinium-DTPA.\n\nMultiplanar 2D and 3D reformations along with subtraction images were\ngenerated on an independent workstation. Prior to the performance of the\nexamination, approximately 200 cc of 1 in 20 solution of GastroMARK to barium\nwas instilled via the rectum through a small-caliber Foley catheter. 1 mg IM\nglucagon was administered to reduce bowel motion.\n\nMRI OF THE RECTUM WITH AND WITHOUT INTRAVENOUS CONTRAST: A circumferential,\nill-defined, heterogeneous, \"carpeting\" mass is demonstrated within the rectum\nmeasuring up to 8-mm thick, located approximately 7 cm superior to the anal\nverge, and spanning inferiorly for approximately 5 cm, with inferior extension\ninto the anus. The more superior aspect of this mass relatively spares the\n___ o'clock positions (standard lithotomy position), but appears completely\ncircumferential along its inferior aspect.

At approximately 11 o'clock, 3 cm superior to the mass (4:26) is a node\nmeasuring 6 mm in greatest short axis dimension, also immediately adjacent to\nthe rectal wall. At 8 o'clock standard lithotomy position, 3.3 cm superior to\nthe superior margin of the rectal mass (4:27) is a lymph node measuring 5 mm\nin greatest short axis dimension. This node is within 3 mm of the mesorectal\nfascia.\n\nWithin the anterior anus extending from the 11 o'clock to 1 o'clock positions,\napproximately 1.8 cm superior to the anal verge, there is an ill-defined area\nof abnormal heterogeneous enhancement with associated small foci of\nsusceptibility, nonspecific but which could relate to changes from recent\nbiopsy.\n\nThere is no evidence of bowel obstruction. The imaged portions of the seminal\nvesicles, prostate, bladder are within normal limits. Several scattered\nsubcentimeter bilateral inguinal and external iliac chain lymph nodes are\ndemonstrated, which do not meet criteria for pathologic enlargement.

metastatic colon cancer. CT negative as was PET\nscan. We are trying to ascertain the local extent ?surgery. Local extent of\nthe rectal cancer.\n\nTECHNIQUE: Multiplanar, multisequential MRI of the pelvis was performed pre-\nand post the administration of 6 mL of Gadavist intravenous contrast. In\naddition, 1 mg of glucagon was given intramuscularly prior to start of the\nexamination.\n\nCOMPARISON: This study is compared to previous CT abdomen/pelvis from ___.\n\nFINDINGS:\nAt and distal to the anastomosis within the rectum the rectal wall is slightly\nthickened with T2 hyperintensity but not increased enhancement, which is\nnonspecific and may be related to prior surgery or other therapy. There is\nredundancy of the bowel at the anastomosis. In the rectal wall particularly\nalong the left anteriorly but also slightly to the right anteriorly there is\nan ill defined area of decreased signal intensity on T2-weighted images that\nhas increased enhancement in the late arterial phase extending from the mucosa\nthrough the anterior wall of the rectum (image 56, series 100) to the left of\nmidline. More T2 hypointense soft tissue extends from the left anterior wall\noutside the rectum and around the left vas deferens. The findings are\nconcerning for tumor extending outside the bowel wall along the left vas\ndeferens, though as surgery has occurred in this area and the remaining\nseminal vesicles and vas deferens are distorted it is hard to differentiate\ntumor from surgical changes. In addition, there is abnormal enhancement more\ninferiorly along the left seminal vesicle which is discontinuous with the more\nsuperior area of enhancement and may be related to either surgical scarring or\na potentially separate focus of malignancy within the pelvis (image 68, series\n100). There are small scattered subcentimetric lymph nodes within the pelvis\nwhich are not enlarged by size criteria (all less than 5 mm).\n\nThere is a small amount of free fluid within the pelvis. There has been\nprevious prostatectomy. There is scarring of the seminal vesicles. There is\na 1.7 cm right epididymal cyst. There are small bilateral hydroceles.\n\nThe localizer sequence demonstrates right renal cysts.\n\nThe bone marrow signal intensity is within normal limits.\n\nIMPRESSION:\n1. Abnormality with increased enhancement within the anterior rectal wall, but\nwith only a slight mucosal component evident by MRI, extends through the\nrectal wall on the left anteriorly and then into and along the left vas\ndeferens. As most of the abnormality is mural and extramural, recurrence at\nthe site of the extensive prior drop metastasis is very possible, and seems\nmore likely than a second primary lesion.\n\n2. Abnormal enhancement more inferiorly along the left seminal vesicle may be\na second focus of malignancy. \n\n3. Small bilateral hydroceles and right epididymal cyst. \n\n4.

The tumor measures 2.5 x 2.5 cm in axial\nplane.\n\nThe mid rectal portion of the tumor extends through the rectal wall and\ninvolves the mesorectal fat, with 5 mm depth of invasion. This corresponds to\na T3B tumor stage. The circumferential resection margin is free of disease at\nthis level. There are engorged enhancing tubular structures noted in the\nright mesial rectal fat compatible with extramural vascular invasion (series\n100:60).\n\nThere are several suspicious spiculated lymph nodes seen in the posterior\nmesial rectal fat measuring up to 4 mm (10:28, 10:26, 10:35). There is also a\nspiculated presacral lymph node seen measuring 5 mm (9:7), highly suspicious\nfor disease involvement. This is compatible with N2 disease.\n\nThere are 2 internal iliac lymph nodes measuring up to 5 mm which are highly\nsuspicious for involvement and will require close attention on surgical\nexploration or follow-up. These are seen on image 36, series 10 and image 45,\nseries 10.\n\nWith respect to the lower rectal component of the mass, there is involvement\nof the internal sphincter and the intersphincteric plane. There is also\nstrong suspicion for involvement of the external sphincter/puborectalis\nmuscle, specifically seen on image 78, series 10 at both the 5 and ___ o'clock\npositions. This corresponds to at least stage III disease, and more than\nlikely represents stage IV disease.\n\nHeterogenous appearance of the central gland of the prostate compatible with\nbenign prostatic hypertrophy.

This\nmay be desmoplastic in nature, with some tethering of the fascia. If these\nregions of tethering are indeed desmoplastic, the CRM in this region would be\napproximately 4 mm. The tumor also abuts the left side of the puborectalis,\nbut with suggestion of a preserved fat plane along most of its course. Along\nthe region of the ano-rectal junction, it is difficult to separate the rectum\nfrom the muscle.\n\nBLADDER AND DISTAL URETERS: Unremarkable.\n\nPROSTATE, SEMINAL VESICLES, AND SCROTUM: The prostate is normal in size. \nSeminal vesicles appear normal. The scrotum is unremarkable.\n\nLYMPH NODES: There is a nodal conglomerate anteriorly along the inferior\nmesenteric drainage (6:13), not well appreciated on previous study. \nPerirectal lymph nodes are largely not seen on today's exam.\n\nVASCULATURE: Visualized vasculature is patent.\n\nOSSEOUS STRUCTURES AND SOFT TISSUES: No focal osseous lesion is identified.\n\nIMPRESSION: \n\n1. Interval decreased size of the primary rectal mass and soft tissue\ndeposits in the left mesorectal fat. Inferiorly, the mass still appears to\nabut the left levator ani muscle, and although it has slightly less bulk than\nbefore, the degree of involvement of this muscle is difficult to assess.\n\n2. Lymph nodes along the inferior mesenteric drainage.\n\nThese findings were reviewed in person with Dr. ___ on ___ at\napproximately 17:30.\n", "rows": [ { "field": "Age", "GPT 5.5 Output": "not

An\nadditional 11 mm focus of enhancement within the left ilium (15:59) is\nunchanged compared to the prior scan.\n\nThere are small bowel loops tethered to the presacral soft tissue at this\nsite, likely secondary to scarring from post treatment changes.\n\nIMPRESSION: \n\n1. Increase in left hemi sacral osseous metastatic lesion now measuring up to\n6.4 cm compared to a prior of 4.4 cm. However there is less intense\nenhancement and less restricted diffusion when compared to the prior scan\ndated ___ raising suspicion that this change may be related to post\ntreatment changes rather than true disease progression. However close\ninterval follow-up is recommended. The exiting left sacral nerve roots\ndemonstrate perineural enhancement, likely due to post treatment changes. \nAnother discrete 1 cm left iliac likely osseous metastasis is stable.\n2. Worsening left greater than right hydronephrosis and proximal hydroureter\ndue to obstruction by retroperitoneal scar tissue at approximately L3 level.\n3. New focal near occlusive short-segment thrombus within the IVC at L3 level\nwith patent distal IVC and bilateral external iliac as well as femoral veins. \nThe thrombus is likely bland given the lack of intrinsic enhancement.\n4.

The patient declined the administration of gadolinium, limiting\nthe characterization of the pelvic soft tissues. In addition, diffusion and\nweighted imaging was performed through the pelvis.\n\nFINDINGS:\n\nThe uterus measures 7.8 cm craniocaudal x 3.6 cm in AP diameter with an\nendometrial stripe thickness of approximately 3 mm. No focal circumferential\nmasses noted in relation to the cervix; however, there is thickening and\nill-defined soft tissue noted circumferentially in the region of the cervix\nand local parameterial invasion by local tumor recurrence is difficult to\nexclude, particularly in the absence of IV contrast (series 5, image 31).\nThere is dilation of the visualised distal ureters bilaterally and they seem\nto narrow at the level of the previously described ill-defined soft tissue\nwith associated cicumferential thicening of the walls of the ureters also at\nthis level (series 3, image 15 and series 3, image 17). Associated left\nhydronephrosis is likely present as well (limited image series 12, image 23). \nWhile findings in the distal ureters may correspond to radiation - induced\nfibrosis in the distal ureters, findings are new since CT examination from\n___ making it suspicious sequellae from local disease recurrence and\nparametrial invasion in the pelvis. Findings in the distal ureters may account\nfor the patient's renal impairment. \n\nBladder is unremarkable with no evidence for air and indeed on within the\nlimitations of this examination of the pelvis, no direct evidence for\nrecto-vaginal or vesico-rectal fistula. \n\nThere is circumferential thickening, submucosal edema and cicatrisation of fat\nnoted in the visualized rectum and sigmoid colon consistent with chronic\ncolitis from known radiation induced colitis (series 3, image 25). \n\nThe ovaries are not visualized. There is no pelvic adenopathy or free fluid. \nThere are bilaterally enlarged inguinal lymph nodes measuring up to 2cm in\ndiameter bilaterally, also new since prior imaging from ___. Given the\nfindings in the pelvis, malignant adenopathy cannot be excluded. The ability\nof these nodes to be percutaneously biopsied could be difficult due to the\nlarge anterior abdominal wall hernia with a large neck containing multiple\nloops of small and large bowel, which is unchanged from prior CT examination\nfrom ___.\n\nBone marrow signal demonstrates fatty infiltration consistent with known\nradiation to the pelvis. \n\nIMPRESSION:\n\n1. Ill-defined soft tissue surrounding the cervix concerning for local\nrecurrence and parametrial invasion within the pelvis. \n\n2. There is incorporation of the distal uteters into this focal region of\nindistinct soft tissue with associated proximal dilatation. This is unlikely\nto be post-radiation changes in the ureters given that the appearances are new\nsince prior imaging from ___ findings are concerning for sequellae from\ntumor recurrence in the pelvis. \n\n3. Though not well-imaged, partial visualization of the left kidney suggests\nhydronephrosis in conjunction with bilateral hydroureter. Recommend renal\nultrasound for confirmation and assessment of the right kidney as well.\n\n4. Bilateral inguinal lymph nodes measuring up to 2cm in short-axis diameter,\nnew since prior imaging from ___, concerning for disease involvement.\nPercutaneous FNA of these lymph nodes could be performed however may be\ntechnically difficult due to the large ventral wall abdominal hernia\ncontaining both small and large bowel loops as described. \n\nSummary of impression were entered into

Please\nassess mass for presence of planes between sacrum and mass and rectum and mass\nfor surgical planning. \n\nCOMPARISON: CT dated ___. \n\nTECHNIQUE: Multiplanar T1 and T2 weighted images were acquired on a 1.5 Tesla\nmagnet including dynamic 3D imaging obtained prior to, during and after the\nuneventful intravenous administration of 8 mL of Gadavist. The patient also\nreceived 1 mg IM glucagon. \n\nFINDINGS:\n\nThere is a 2.2 (transverse) x 2.2 (AP) x 1.9 (CC) cm mass within the presacral\nspace on the right side, which is increased slightly in size since the\nprevious CT (previously 2 x 1.8 x 1.7 cm). This mass is immediately adjacent\nto multiple foci of susceptibility artifact consistent with surgical clips\nfrom previous surgery. It is T2 hyperintense (7:16 and 4:16), is hypointense\non the pre-contrast fat-saturated T1-weighted sequence (9:56) and demonstrates\navid enhancement post-contrast (1001:56). It is 9 mm posterolateral to the\nupper rectum on the right side (7:16 and 1001:57). It is immediately abutting\nthe right side of the sacrum at the S3-4 vertebral level, anterior to the\nright S3 neural exit foramen, but it is not invading the sacrum. It is also\nabutting the right piriformis muscle but, again, it does not appear to be\ninvolving the right piriformis muscle. \n\nThere are two further lesions identified on the T2-weighted sequences and they\nmeasure 3.6 x 2.1 cm in the right iliac fossa adjacent to the cecum (6:35 and\n5:1) and 1.2 cm in the small bowel mesentery (5:2 and 6:29). These are\nsimilar in appearance to the lesion within the pelvis on T2WI. On the\nprevious CT dated ___, they were isodense to the small bowel and\ninconspicuous. They are unchanged in size since the previous CT. There is a\n1.2 x 0.8 cm left common iliac lymph node which is also unchanged in size\nsince the previous CT (5:10). \n\nThe bladder appears unremarkable. The prostate gland and seminal vesicles are\nwithin normal limits. The rectum and sigmoid colon are unremarkable. Limited\nevaluation of the bony pelvis is unremarkable. \n\nIMPRESSION:\n\n1. 2.2 x 2.2 x 1.9 cm presacral mass on the right side which is consistent\nwith recurrent disease and has increased slightly in size since the previous\nCT. It is approximately 9 mm from the rectum and is immediately abutting the\nright side of the sacrum at S3-4. \n\n2. Two further lesions are identified that appear consistent with metastatic\ndeposits - these lie adjacent to the cecum (3.6 x 2.1 cm) and within the small\nbowel mesentery (1.2 cm). These are stable in size since the previous CT.\n\n3. 1.2 x 0.8 cm left common iliac lymph node which is also unchanged in size\nsince the previous CT.\n\n", "rows": [ { "field": "Age", "GPT 5.5

For example along the left\nlateral aspect of the lesion at ___ o'clock, it measures approximately 16 mm\nin width. It previously measured up to 26 mm in width. Additionally, around\nthe periphery of the lesion, the signal has decreased, and is now all low\nsignal on the T2 weighted images. This suggests fibrotic changes. Finally,\nthere are some areas that are high signal on the T2 weighted images (6, 13 and\n6, 15).

There is no clear fat plane between the\nmass and this loop, on the wall of the small bowel is very slightly irregular\n(6, 6). The tissue of the mass in this location is low signal on the T2\nweighted images, so it may be just represent fibrosis, though some small\namount of viable tumor is difficult to exclude.

There is a 17 mm fibroid along the posterior\naspect of the uterus (6, 13). The endometrium measures 4 mm, though there is\na small amount of heterogeneous T2 hypointense material within the endometrium\n(6, 11). The cervix and vaginal canal are grossly normal.\n\nThe bladder is not distended, which limits evaluation. There is no focal wall\nthickening or evidence of a mass.

colon ca here with BRBPR abd pain and\nrectal ma// further characterize liver lesion (?met vs primary) and rectal\nlesion (CA vs abscess amenable to drainage?)\n\nTECHNIQUE: T1- and T2-weighted multiplanar images of the abdomen and pelvis\nwere acquired in a 1.5 T magnet.\nIntravenous contrast: 6 mL Gadavist.\n\nCOMPARISON: CT scan of the abdomen and pelvis dated ___\n\nFINDINGS: \n\nLower thorax: The lung bases are clear. No pleural pericardial effusion.\n\nLiver: Evaluation of the liver is limited by breathing motion artifact. \nHowever, there is a T1 hypointense, mildly T2 hyperintense lesion within\nhepatic segment 2 corresponding to the lesion identified on CT and measuring\napproximately 12 mm (axial series 5, image 23; axial series 4, image 12). \nThis lesion is hypoenhancing to background liver parenchyma on the arterial\nphase and appears to demonstrates similar enhancement to background liver on\nthe more delayed phases (axial series 1201, image 33). There is mild apparent\ndiffusion restriction (axial series 6, image 26; axial series 600, image 6). \nNo other liver lesions are identified. The background liver is non cirrhotic.\nNo hepatic steatosis.\n\nBiliary: The gallbladder is contracted. Diffuse gallbladder adenomyomatosis. \nNo biliary ductal dilatation.\n\nPancreas: Normal T1 signal of the pancreas. No pancreatic mass or ductal\ndilatation.\n\nSpleen: No splenomegaly.\n\nAdrenal Glands: The adrenal glands are normal in size and morphology.\n\nKidneys: Subcentimeter right-sided renal cortical cysts. No hydronephrosis.\n\nGastrointestinal Tract: The stomach is unremarkable. The small bowel and\ncolon are normal in caliber. Sigmoid diverticulosis.\n\nThere is a 5.8 x 6.6 cm T2 hyperintense mass arising from the posterior aspect\nof the proximal rectum/rectosigmoid junction which demonstrates diffusion\nrestriction and heterogeneous enhancement with areas of central\nhypoenhancement. This mass extends into the presacral space and directly\nabuts the sacrum. Again noted is abnormal enhancement extending from this\nmass through the right sciatic notch and involving the right gluteal\nmusculature. Within this area of abnormal enhancement, there are 2 linear\nhypoenhancing structures which may represent fistulization or thrombosed\nvessels.\n\nPelvis: Presacral mass as described above with involvement of the right\nsciatic notch and right gluteal musculature. The bladder and prostate do not\nappear to be involved by tumor.\n\nLymph Nodes: 8 mm pelvic lymph node adjacent to the dominant mass is\nsuspicious for metastatic disease.\n\nVasculature: Focally ectatic infrarenal abdominal aorta is again noted. No\nabdominal aortic aneurysm. Extensive atherosclerotic disease is demonstrated\nin the bilateral common iliac arteries, and left more than right external\niliac arteries. The right internal iliac artery and vein are encased by the\npelvic mass.\n\nOsseous and Soft Tissue Structures: Abutment of the sacrum by the patient's\npelvic mass, which on recent CT appear to demonstrate mild irregularity of the\ncortex but no frank invasion. Some asymmetric enhancement suggesting\ninfiltration along the anterior aspect of the right first sacral foramina is\nseen. (Series 14, image 72). Abnormal enhancement involving the right\ngluteal musculature as described above, suspicious for infiltrative local\nextension of tumor.\n\nIMPRESSION:\n\n\n1. 6.6 cm centrally hypoenhancing tumor arising from the posterior aspect of\nthe rectosigmoid junction most in keeping with recurrent disease, with\nabutment of the sacrum and mild cortical irregularity but no definite osseous\ninvasion.\n2. Abnormal enhancement extending through the right sciatic notch to involve\nthe right gluteal musculature is suspicious for infiltrative extension of\ntumor, with linear hypoenhancing structures which may represent small fistula\ntracts or encased thrombosed vessels.\n3. 8 mm left-sided high rectal lymph node is suspicious for local nodal\ninvolvement.\n4. 12 mm hepatic lesion within segment 2 remains indeterminate. Given very\nlimited assessment on dynamic post-contrast imaging due to motion, consider 4\nphase liver CT or PET-CT to further evaluate possibility of hemangioma versus\nmetastasis in this region. Alternatively, if there are prior CT studies for\ncomparison this would be helpful to evaluate change or stability over time.\n", "rows": [ { "field": "Age", "GPT 5.5 Output": "not mentioned", "GPT

CONTRAST:\nArising from the junction of the mid to upper rectum, approximately 9 cm from\nthe anal verge, is a 14 mm polypoid mass demonstrating relatively low signal\nintensity on T2 weighted sequences (series 6 image 21), with early enhancement\nof the intraluminal portion (series 1,101 image 69) followed by enhancement of\nthe stalk on delayed phases (series 1,102 image 67). The mass appears\nconfined within the mucosa/submucosa, as the overlying muscularis layer\nappears completely intact. This lesion corresponds to the endoscopically\nbiopsied polyp with a reported focus of adenocarcinoma.\n\nIrregular thickening of the mid and lower rectum, predominantly along the\nposterior aspect (series 6 image 26) extends at least 3.6 cm (series 4 image\n15), terminating at the superior aspect of the internal sphincter. This\nrepresents an area of multiple polyps seen on endoscopy, biopsied as adenomas.\n\nMultiple mesorectal lymph nodes are more than 2 mm deep to the circumferential\nresection margin. The irregular morphology of several of these nodes is\nsuspicious for tumor involvement. For example, three enlarged\nirregular-appearing lymph nodes along the left superior ___ fat\n(series 1,101 image 36, 47, 54) measure up to 7 mm in length. Other lower\nmesorectal lymph nodes are less specific, but measure at least 5 mm (series\n1,101 image 78, 74, 77), also suspicious.\n\nThere is moderate sigmoid diverticulosis (series 4 image 9). There is no\nintrapelvic free fluid. An ill-defined focus of decreased signal intensity\nalong the right peripheral zone of the prostate on T2 weighted sequences\n(series 6 image 27) is better seen on the dedicated MR prostate examination\nfrom ___, compatible with known prostate adenocarcinoma.

rectum (8:1 dilution of barium\nand GastroMARK).\n\nMultiplanar 2D and 3D reformations and subtraction images were generated on an\nindependent workstation.\n\nCOMPARISON: CT abdomen and pelvis ___.\n\nFINDINGS:\n\nThere is a polypoid mass originating approximately 15 cm from the anal verge\nwithin the sigmoid colon. The proximal extent of the mass is difficult to\nidentify on T2-weighted images due to collapse of the proximal sigmoid colon. \nHowever, post-contrast administration, abnormal intraluminal enhancement is\nlimited to the distal 3.5-4 cm of this segment. There is no definite extension\nof the tumor through the muscularis into the serosa and perisigmoid fat,\nhowever, this assessment is slightly limited by multiple factors including\nmotion artifact degenerating some of the post-contrast and high-resolution\nT2-weighted images, as well as morphologic changes within the sigmoid colon\nand adjacent region related to prior bouts of diverticulitis. \n\nThere is moderate sigmoid diverticulosis without acute diverticulitis with\nprobable muscular hypertrophy of the proximal sigmoid colon, proximal to the\nintraluminal mass. There is a moderate amount of chronic perisigmoid\ninflammatory changes with tethering of adjacent small bowel loops. There is\nalso an enhancing tract extending anterolaterally to the right pelvis which\nappears to contain air, possibly representing a sinus tract with inflammation\n(13:60). There is no definite connection to small bowel or bladder to\nrepresent a fistula, although evaluation is somewhat limited. These findings\nlikely represent the sequala of prior sigmoid diverticulitis and correspond to\nthe area of prior diverticulitis as noted on the comparison CT. No pelvic\nabscess. \n\nThere is an 8-mm round central pelvic lymph node (series 12, image 51) with\nslightly heterogenous enhancement. This may be reactive due to the ongoing\nadjacent inflammation, however, metastatic involvement cannot be excluded out.\nThere is a 5-mm left external iliac node.

T2-weighted images were acquired on a 1.5\nTesla magnet including dynamic 3D imaging obtained prior to, during and after\nthe uneventful intravenous administration of 0.1 mmol/kg (15 mL) of\ngadolinium-DTPA. Approximately 100 mL of rectal contrast was administered in\nthe form of GastroMARK diluted in Redi-CAT. In addition 1 mg of glucagon was\nadministered IM to reduce bowel motion.\n\nCOMPARISON: No prior studies available for comparison.\n\nFINDINGS:\nThe rectal contrast fills the distal rectum; however, it does not pass\nproximal to a tight stricture approximately 12 cm from the anal verge (3:16). \nAt this level there is abnormal mucosal thickening of the rectum with\nenhancing tissue extending posteriorly to the mesorectal fascia (6:11) and\nalso extending to the peritoneal reflection anteriorly (6:12). The abnormal\ntissue extending posteriorly retracts the mesorectal fascia (___:55) which\nmay be due to desmoplastic reaction, nonetheless there does appear to be\nenhancing tissue also extending in this direction. No clear fat plane can be\ndelineated between the rectum and the uterus in this region (___:45). No\nfrank invasion of the uterus can be seen; however, invasion cannot be excluded\nbased on this study. In the left adnexal region, there is a lobulated\npredominantly T2 hypointense mass measuring 3.4 x 1.8 cm. This cannot be\nseparated from the left ovary which is not clearly visualized. This mass has\nvery similar imaging characteristics to the rectal mass; however, this abuts\nthe mesorectal fascia externally and is not contained within it. The\nappearances are most suggestive of an ovarian metastasis from the rectal\ncarcinoma. In the right adnexal region, there is a 4.1 x 2.4 cm predominantly\nT2 hyperintense mass (5:27). This traverses the mesorectal fascia (6:4). \nAgain, the right ovary cannot be separated from this lesion. The appearances\nsuggest a right ovarian metastases; however, given that this appears to\npenetrate the mesorectal fascia, this could reflect lymph node metastasis has\ninvaded the right ovary directly. A 5-mm mesorectal lymph node is seen\n(6:16). No additional pelvic lymphadenopathy can be appreciated. The uterus\nis anteverted and anteflexed. The endometrium is heterogeneous in signal\nintensity with a 1.1-cm endometrial stripe. Arising anteroinferiorly from the\nuterine body, there is a 5-mm subserosal hypointense lesion which is\nhypointense on T2 and demonstrates peripheral enhancement post-contrast\n(903B:16). While this could reflect a pedunculated fibroid, a uterine\nmetastasis cannot be excluded. Again this could be further evaluated on\nultrasound. The visualized osseous structures are unremarkable.\n\nIMPRESSION:\n1. Likely T4 rectal tumor 12 cm from the anal verge with tumor extending both\nanteriorly and posteriorly through the mesorectal fascia and into the\nperitoneal reflection. The abnormal tissue cannot be definitely separated\nfrom the uterus; however, no frank invasion is seen.\n2. Bilateral ovarian masses as described very concerning for metastatic\ndisease with the right mass involving the ovary and on both sides of the\nmesorectal fascia.\n3.

Restaging. Outside PET in system\n\nTECHNIQUE: T1- and T2-weighted multiplanar images of the pelvis were acquired\nin a 1.5 T magnet.\nIntravenous contrast: 10 mL Gadavist.\n\nCOMPARISON: PET-CT ___ performed at an outside institution. MRI\nabdomen and pelvis with and without contrast ___\n\nFINDINGS: \n\nA portion of remaining rectal stump is identified. Adjacent to the left\nposterior aspect of and inseparable from the rectal stump is a nodular,\nlobulated lesion that measures 2.6 x 2.0 cm that is heterogeneous on T2Wi and\nshows restricted diffusion as well as heterogeneous enhancement with washout,\nconcerning for recurrent/residual disease. This nodule abuts the left\npiriformis musculature as well as the S2 and S3 nerve roots (07:36).\n\nContiguous with the rectal stump and extending into the pelvis more\nsuperiorly, there is extensive diffuse circumferential low signal intensity on\nT2 weighted images with a rim of early and prolonged enhancement, an\nappearance that is consistent with chronic organized collection, athough some\ncomponent of involvement by tumor can not be excluded. A superior extension\nof the collection, which appears to be in communication with the rectal stump,\nextends to the sacral promontory at the midline terminating in an area of\nsurgical clips, and abuts the left common iliac vein which is patent. A\nsecond track extends from the right posterolateral aspect of the rectal stump\nto the levator plate ((100:84). An additional tract is seen extending\nposteriorly to the coccyx (100:61). There is no obvious abnormal signal\nwithin the coccyx itself.\n\nThe distal ureters are nondilated. The left ureter is partially surrounded by\nT2 hypo intense fibrotic reaction (05:13) the bladder is unremarkable.\n\nThe prostate is abutted by the rectal stump. The bilateral seminal vesicles\nare drawn into the area of fibrotic change and enhancement (05:19).\n\nNumerous rounded sub cm perirectal lymph nodes are suspicious based on\nmorphology (10:114, 10:113). Sub cm right external iliac chain lymph nodes\nare slightly increased in size (7 mm on 10:79 and 9 mm on 10:98). These may\nbe reactive.\n\nThere are at least 3 unchanged scattered bone islands. No suspicious osseous\nlesions are seen.\n\nIMPRESSION:\n\n\n1. 2.6 x 2.0 cm nodular area with washout along the left posterior aspect of\nthe rectal stump concerning for recurrent/residual disease. This nodule abuts\nthe left piriformis musculature as well as the S2 and S3 nerve roots.\n2. Findings consistent with a complex organized chronic collection in\ncommunication with the rectal stump with superior extension to the sacral\npromontory and additional tracts are seen from the right posterior lateral\naspect of the rectal stump to the levator plate and also extending posteriorly\nto the coccyx. Findings are favored to represent chronic organized collection\nwith extensive rim of fibrosis, noting that due to contiguity, interspersed\ninvolvement with tumor can not be excluded.\n3.

to reduce bowel motion, and barium was\ninstilled via a rectal catheter to distend the rectum.\n\nCOMPARISON: CT abdomen and pelvis, ___.\n\nFINDINGS:\n\nArising approximately 12 cm from the anal verge, there is an eccentric,\nhemi-circumferential notably T2 hyperintense mass which extends from the high\nrectum to the rectosigmoid junction. This mass has predominantly intraluminal\nextension, involving a craniocaudal distance of approximately 6.5 cm. No\nupstream dilatation can be appreciated, however. No definite transmural\nextension can be appreciated. \n\nNo enlarged perirectal lymph nodes. There are two enlarged right common iliac\nnodes measuring 1cm (1001:88) and 8mm (1001:100). Small bilateral external\niliac nodes are symmetric and have a benign configuration measuring 7 mm in\nshort axis (1002:48). A right common femoral lymph node measures 1.1 cm\n(1002:33); however, this has a fatty hilum suggesting a benign etiology. \n\nThe urinary bladder and prostate are unremarkable in appearance.

pelvis were acquired\nin a 1.5 T magnet.\nIntravenous contrast: 6 mL Gadavist.\n\nCOMPARISON: There are no comparison studies listed.\n\nFINDINGS: \n\nUTERUS AND ADNEXA:\n\nThe uterus is retroverted and measures 3.9 x 5.1 x 7.2 cm.\n\nThere is a circumferential mass in the cervix measuring 3.3 x 2.9 x 3.4 cm. \nThe mass causes cervical stenosis resulting in hematometra.\n\nThere is disruption of the hypointense cervical ring with stranding of\nsurrounding fat bilateral consistent with bilateral parametrial spread.\n\nThere is loss of the fat plane between the cervical mass and the posterior\nwall of bladder with thickening of the adjacent muscular bladder wall with\nincreased T2 signal (series 4, image 21) as well as increased signal on DWI\nimaging (series 7, image 22 and series 8, image 17) suggesting bladder wall\ninvasion. There is no extension through the mucosa/into the bladder lumen.\nThe cervical tumor abuts the mesorectal fascia posteriorly with possible\nextension into the mesorectal fat. No clear involvement of the rectal wall.\n\nLesion involves the upper ___ of the vagina with thickening of the vaginal\nvault on the left.\n\nNote is made of severe right hydronephrosis on the localization scan\n(suggesting pelvic wall invasion) please see description below.\n\nThe right ovary is visualized and appears within normal limits.\nThe left ovary is visualized and appears within normal limits.\n\nNo significant pelvic free fluid.\n\nLYMPH NODES: Subcentimeter pelvic sidewall lymph nodes are not enlarged or\novertly suspicious.\n\nBLADDER AND DISTAL URETERS: There is loss of the fat plane between the\ncervical mass and the posterior wall of bladder with thickening of the\nadjacent muscular bladder wall with increased T2 signal (series 4, image 21)\nas well as increased signal on DWI imaging (series 7, image 22 and series 8,\nimage 17) suggesting bladder wall invasion. There is no extension through the\nmucosa/into the bladder lumen.\n\nNote is made of severe right hydronephrosis on the localization scan. \nAlthough there is no associated right hydroureter, obstruction is thought to\nbe most likely secondary to known cervical malignancy and hydronephrosis in\nthe absence of hydroureter likely representing burnt-out right hydronephrosis.\n\nRECTUM AND INTRAPELVIC BOWEL: Involvement of the mesorectal fascia and\nsuspected mesorectal fat as described above. No definite rectal involvement.\nThe visualized bowel is nonobstructed. There is diverticulosis of the sigmoid\ncolon.\n\nVASCULATURE: There is an incompletely visualized aorta-bifemoral stent in situ\nwith thrombosis of the right common and external iliac artery graft. Right\ninternal iliac vessels receive collateral supply. There is a a fem-fem bypass\ngraft in place which is patent and supplies the right femoral artery. The\nleft common iliac, external iliac and femoral grafts are patent. There is\nstenosis of the left internal iliac artery. There is a small fluid collection\nmeasuring 1 cm (series 3, image 5) adjacent to the proximal aspect of the\ngraft which is most likely postsurgical in nature.\n\nOSSEOUS STRUCTURES AND SOFT TISSUES: There are no suspicious osseous.\n\nIMPRESSION: \n\n1. Cervical mass in keeping with known cervical cancer with extension into\nthe left upper third of the vagina, bilateral parametrial invasion, severe\nright-sided hydronephrosis as well as bladder wall involvement. Findings\nsuggest a T4a tumor. No suspicious regional lymph nodes (N0). No metastasis\nvisualized within the confines of a pelvic MRI.\n2. Severe/burnt-out right hydronephrosis is likely due to known cervical\nmalignancy.\n3. Thrombosis of the right common and external iliac limb of the\naorto-bifemoral artery graft with patent fem-fem bypass graft.\n4.

comparison.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted imaging were acquired on a 1.5\nTesla magnet including dynamic 3D imaging obtained prior to, during, and after\nthe uneventful intravenous administration of 6 mL of Gadavist. In addition,\n60 cc of barium was administered per rectum via rectal tube, and 1 mg of\nintramuscular glucagon was administered to reduce bowel motion.\n\nFINDINGS: \n\nThere is a large 7.5 x 2.5 x 7.7 cm intraluminal polypoid lesion arising\nwithin the mid to lower rectum with the distal margin approximately 9 cm from\nthe anal verge (series 4, image 16). It extends over a craniocaudal distance\nof approximately 7 cm. The majority of this lesion is posterior and extends\nfrom approximately ___ o'clock in the supine position (series 11B, image 160).\nIn the mid rectum the lesion is seen to abut the anterior wall of the rectum\n(series 11B, image 163 and series 4, image 21). The majority the lesion as\npreviously described appears intra-luminal with an intact appearing rectal\nwall identified throughout. However, assessment for invasion through the\nmuscularis propriat is severely limited due to lack of intraperitoneal and\nperirectal fat likely due to the patient being a known vasculopath, as well as\nmotion in this examination. Indeed the mesorectal fascia margin cannot be\nevaluated in this patient due to again the lack of intraperitoneal pelvic fat.\n\n\nThere is no significant pelvic side wall adenopathy. As previously stated,\nthe presence of perirectal lymph nodes cannot be evaluated again due to lack\nof intraperitoneal pelvic fat. \n\nVisualized portion of the bladder is unremarkable apart from a small posterior\ndiverticulum (series 4, image 17). The prostate measures approximately 3.5 cm\ncraniocaudal x 1.9 cm in AP diameter. Visualized remainder of sigmoid colon\ncannot be evaluated due to bowel motion at this level. Evaluation of the\nvasculature demonstrates aneurysmal dilatation noted at the proximal\nanastomosis in the region of the right groin measuring 1.6 x 1.6 cm (series\n11B, image 145). \n\nBone marrow signal is unremarkable. There is deficiency noted of the spinal\narch in the lower lumbar / upper sacral spine which may represent either a\nspina bifida occulta defect versus laminectomy defect if there has been a\nprior history of surgery in this region. Multiple Tarlov's cysts are also\nnoted in situ here (series 4, image 19).\n\nIMPRESSION:\n\nLarge endoluminal polypoid lesion within the mid to lower rectum without gross\ninvasion of tumor through the rectal wall. However, assessment for invasion\nthrough the muscularis is severely limited due to lack of intraperitoneal fat\nand motion-related artifact. \n\nFindings and limitations were discussed with Dr. ___

pelvis were acquired\nin a 1.5 T magnet.\nIntravenous contrast: 8 mL Gadavist\n\nCOMPARISON: CT abdomen and pelvis ___\n\nFINDINGS: \n\nUTERUS AND ADNEXA:\n\nThe uterus is anteverted and measures 10.1 x 4.7 x 6.1 cm. Numerous small\nfoci of T2 hyperintensity is noted throughout the uterine wall, suggestive of\nadenomyosis.\nThe endometrium is thickened for patient's age and measures 12 mm.\nThe junctional zone is thickened.\n\nThere are 2 clusters of cystic and solid mass in the right pelvis. The more\nposterior cluster in the adnexal region measures 5.5 x 3.4 x 3.8 cm and has\ncystic and vascular component and appears to likely arise from the right\novary. T2 hypointense components are a notable aspect of the solid component,\nand was not calcified on prior CT. A portion of the solid component\nhyperenhances after contrast administration.\n\nThe more anterior cluster measures 5.5 x 2.9 x 3.3 cm and appears similar in\nmorphology on T2 weighted images, however does not have hypervascular\ncomponent and prior CT showed large component of heavy calcification. This\ncluster is intimately related to the adjacent small bowel loops and peritoneal\nscarring which extends to the uterus and anterior abdominal wall, and does not\nappear to clearly communicate with adnexal structures or uterus.\n\nThe left ovary is not separately visualized.\n\nNo free pelvic fluid is identified.\n\nLYMPH NODES: No pelvic lymphadenopathy.\n\nBLADDER AND DISTAL URETERS: Unremarkable.\n\nRECTUM AND INTRAPELVIC BOWEL: A 14 mm T2 hyperintense structure in the rectum\nis consistent with known rectal polyp.\n\nOSSEOUS STRUCTURES AND SOFT TISSUES: No worrisome lesion is identified.\n\nIMPRESSION: \n\n1. Right adnexal mass with cystic and vascular component appears to arise\nfrom the right ovary. Fibrous component is suggestive of fibrothecoma or\nfibroma. ___ tumor may also have similar appearance. Gynecology\nconsultation is recommended for excisional biopsy.\n\n2. Another solid and cystic mass is located more anteriorly, tethered to the\nanterior abdominal wall in the right hemipelvis. This mass appears similar to\nthe more posterior lesion, but does not have vascular component. However, on\nthe prior CT, it did have a component of heavy calcification. Left ovary is\nnot separately identified, and this mass may represent tethered and displaced\nleft ovarian mass. If ovarian origin, differential is similar as the more\nposterior lesion, though ___ tumor may be higher in the differential due\nto the degree of calcifications. Evaluation for excisional biopsy is again\nrecommenced.\n\n3. Endometrium is thickened for patient's age. Endometrial biopsy is\nrecommended.\n\n4. Foci of T2 hyperintensity throughout the uterine wall within\nthickened/indistinct junctional zone is suggestive of adenomyosis.\n\n5. A 14 mm T2 hyperintensity in the rectum is consistent with known rectal\npolyp.\n\nRECOMMENDATION(S): Gynecology consultation is recommended for excisional\nbiopsy of the right adnexal mass as well as

of the pelvis with and without contrast\n\nINDICATION: ___ year old man with rectal adenocarcinoma, several polyps on\ncolonoscopy today. Would like to stage cancer w/o doing EUS using MRI //\nPlease do MRI of the pelvis with contrast, rectal mass protocol.\n\nTECHNIQUE: Multiplanar MRI of the pelvis is obtained at 1.5 Tesla per the\nrectal mass protocol. T1 and T2 weighted sequences are acquired both pre and\npost administration of 11 mL of ProHance.\n\nCOMPARISON: None\n\nFINDINGS: \n\nThere is a rectal mass with epicenter within the mid rectum, approximately 7\ncm above the anal verge. This has approximately 3.5 cm of caudocranial\nextension with the distal/ inferior margin measuring approximately 2.6 cm\nabove the superior aspect of the internal sphincter (3:15). The mass is almost\ncircumferential, extending from approximately 2 o'clock to 3 o'clock at the\nsuperior margin (5:13) and 12 o'clock to 6 o'clock at the inferior margin\n(5:18). The mass is T2 hypointense, T1 intermediate in signal (similar to\nskeletal muscle), demonstrates restricted diffusion and diffuse low grade\nenhancement. There is irregularity of the mural margins with stranding within\nthe perirectal fat consistent with extramural extension. There is no\nmacroscopic tumor extension to the mesial rectal fascia.\n\nThere is however a 2.4 cm fluid collection right posterolateral to the\nepicenter of the tumor which extends to the lateral mesorectal fascia (5:12).\nThis is centrally T2 hyperintense, T1 hypointense, restricted in diffusion and\nwithout enhancement. The peripheral rind is T2 hypointense, T1 hyperintense\nand enhancing. This structure is consistent with a focal abscess suggestive of\nmicroperforation, and seeding of tumor is certainly not excluded.\n\nThere is a single morphologically abnormal lymph node, which is enlarged to\n13mm, abnormally round in contour, T2 hypointense, T1 intermediate in signal,\nhas restricted diffusion and heterogenous enhancement. This is located along\nthe right internal iliac chain, best seen on series 5, image 3, and is\nconsistent with regional nodal metastasis. Additional tiny nodes are noted\nmore superiorly, none greater than 5mm in size, and therefore nonspecific.\n\nNo additional distal lymphadenopathy is identified. There is no extramural\nvascular invasion.\n\nThe prostate is normal in size but demonstrates a nonspecific abnormality\nwithin the peripheral zone of the left apex. As seen on series 5, image 19,\nthere is a masslike T2 hypointensity which bulges the prostatic contour and\nextends to the anterior the lower rectum, without intervening fat plane. While\nthe appearance on T2 weighted imaging is highly concerning for prostatic\nmalignancy, there is no restricted diffusion or concerning perfusion (no\nhyperenhancement or washout). This may be on the basis of prostatic\ncalcification. Correlation with PSA and potential endorectal ultrasound and\nbiopsy is recommended. The anterior rectal wall at this level is has no\nmacroscopic rectal tumor which would impede access for prostate biopsy.\n\nThe bladder is notable for gas within the lumen.\n\nThere are degenerative changes of the lower lumbar spine.\n\nExtensive subcutaneous edema is seen diffusely, and may be related to volume\noverload, hypoalbuminemia, or other causes.\n\nIMPRESSION: \n\nMidrectal mass with extramural extension but not to the mesorectal fascia. \nThere is a signal abnormal regional right internal iliac node. Findings are\noverall consistent with T3 N1 stage by imaging. There is evidence of\nmicroperforation based on a focal adjacent abscess which extends to the\nmesorectal fascia laterally.\n\nNonspecific abnormality of the peripheral zone of the prostate at the left\napex, with T2 appearance concerning for malignancy but other imaging\ncharacteristics suggesting against. Correlation with PSA, and consideration\nof endorectal ultrasound with potential biopsy is recommended. There is no\nrectal tumor involving the adjacent anterior wall which would preclude biopsy.\n", "rows": [ { "field": "Age", "GPT 5.5 Output": "not mentioned", "GPT Output, modified by Annotator

MRI for\npreoperative staging.\n\nCOMPARISON: None available in the ___ system.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted images were acquired on a 1.5 T\nmagnet, including dynamic 3D imaging, obtained prior to, during, and after the\nuneventful intravenous administration of 0.1 mmol/kg (17 mL total of\ngadolinium-DTPA). A dilution of GastroMARK and Readi-Cat was administered\nrectally. 1 mg of glucagon was also given.\n\nRECTAL MRI WITH INTRAVENOUS CONTRAST: Following the course of the rectum, the\nproximal margin of a mid rectal lesion is located ~7.5-8 cm above the anal\nverge. Using a measurement that would follow the course of a rigid scope or\ntransducer, the proximal margin is ~6 cm from the anal verge. The lesion\nextends over a length of 4 cm in the mid rectum (3:13). Axial images\ndemonstrate approximately 60% involvement of the circumference of the mid\nrectum. The lesion is centered about the right anterior lateral wall of the\nmid rectum from the 7:00 - 1:30 position. The maximum intraluminal thickness\nof the lesion is 12 mm in the lower aspect (5:23). The inferior-most regions\nof the lesion involve portions of the rectum which are close to apposed to the\nlevator ani (4:21).\n\nAlong the margin of the rectal wall, there are areas of T2 hypointensity which\nare most suggestive of a desmoplastic reaction. No definite extension of\ntumor into mesorectal fat is noted, but given some of the very subtle\nlobulations in this region, early T3 disease cannot be excluded. \n\nMultiple lymph nodes are identified in the perirectal region. Axial images\ndemonstrate an 8 mm lymph node posteriorly, abutting or nor more than 2 mm\nfrom the right posterior mesorectal fascia (5:17 and 6:28). The previously\ndescribed lymph node demonstrates avid enhancement on post-contrast images\n(8:29). A midline posterior lymph node is located 7 mm from the mesorectal\nfascia and a right lateral lymph node which is smaller is 8 mm from the\nmesorectal fascia. An enlarged right common femoral lymph node measures 11 mm\nand demonstrates post-contrast enhancement (5:20). Multiple other scattered\nlymph nodes are identified, some extending superiorly to the sacral\npromintory(4:19, 31) (5:9, 10) (6:14, 20, 24).\n\nThe bladder is normal in appearance without focal wall thickening or\nintraluminal filling defect. A calcification is identified within the mid\nseminal vesicle which is otherwise unremarkable (5:20). Incidental note is\nmade of a cystic lesion in the anterior left acetabulum (5:22), possibly\ndegenerative subchondral cyst.\n\nIMPRESSION:\n\n1. Mid rectal mass extending over a 4 cm length and 60% circumferential, with\nthe proximal margin ~6 cm from the anal verge. The most inferior aspects of\nthe tumor involve portions of the rectum which abut the levator ani. No\ndefinite invasion of the perirectal fat by the primary lesion is noted though\ndesmoplastic reaction is present. Findings most suggestive of T2 lesion; but\nseveral subtle lobulations are seen at is external contour, for which early T3\ndisease cannot be excluded.\n\n2. Scattered perirectal lymph nodes, the largest in the right posterior\nregion abutting the mesorectal fascia (CRM = 0).\n\n3.

___\n\nFINDINGS: \n\nRECTUM AND BOWEL:\nSimilar to the prior study, there is recurrent low rectal cancer with\nextramural extension and vascular invasion. The thickening of the distal\nrectal wall with nodular extramural extension is similar in extent to the\nimmediate prior study with extension superiorly into the left of midline to a\nconfluent area of enhancing restricting nodularity likely representing a\ncombination of vascular involvement and nodal disease measuring up to 2.7 x\n2.4 cm, previously 2.7 x 2.0 cm when measured in similar planes (04:16). This\narea appears similar in overall size with unchanged broad contact with the\nmesorectal fascia but slightly more confluent when compared with the immediate\nprior study. There is proximal extension of abnormal enhancement and\nrestricted diffusion likely representing tumor in vein extending superiorly\nfrom this nodal conglomerate. A similar enhancing restricting tubular deposit\nHope malignancy likely representing tumor in vein is seen on the contralateral\nside, also in contact with the mesorectal fascia (04:17). Small regional\nnodes are grossly similar.\n\nSeparate from the primary rectal mass and the superior nodal conglomerate,\nthere are new enhancing nodules with the upper vagina that demonstrate\nrestricted diffusion early hyperenhancement washout suspicious for additional\nsite of a metastatic involvement. The largest nodule measures up to 1.8 cm\n(9:71, 11:34). Inferior this larger nodule there is an anterior extension of\nabnormal early hyperenhancement and washout and restricted diffusion that\nextends to partially surround the posterior aspect and left side of the\nurethra measuring up to 2.2 cm (9:84; 04:28).\n\nUTERUS AND ADNEXA:\nThe uterus is retroverted and measures 4.9 x 2.1 x 3.6 cm.\nThe endometrium is normal in thickness for age and measures less than 2 mm.\nThe junctional zone is not thickened.\n\nThe right ovary is visualized and appears within normal limits.\nThe left ovary is visualized and appears within normal limits.\n\nTrace pelvic free fluid is within physiologic limits.\n\nBLADDER AND DISTAL URETERS: Unremarkable.\n\nVASCULATURE: Unremarkable.\n\nOSSEOUS STRUCTURES AND SOFT TISSUES: Tarlov cysts are noted in the sacrum,\nunchanged.

rectal cancer protocol.\n\nTECHNIQUE: T1- and T2-weighted multiplanar images of the pelvis were acquired\nin a 1.5 T magnet.\nIntravenous contrast: 9 mL Gadavist\n\nCOMPARISON: CT abdomen dated ___\n\nFINDINGS: \n\nApproximately 8.2 cm from the anal verge, there is a 3.7 cm\nhemi-circumferential mass extending from approximately 10 to 5 o'clock. There\nis likely involvement of the muscularis propria, including an area extending\nanteriorly, from approximately 10 to 1 o'clock, 9.4 cm from the verge, where\nthe outer T2-hypointense margin of muscularis propria is markedly thinned and\npoorly visualized. However, there is no definite extension of tumor beyond\nthe margins of the muscularis propria. Also observed are linear, enhancing,\nT2 hypointense spiculations extending from the tumor margin centered at\napproximately 1 o'clock which likely represent fibrosis. The findings are\nmost suggestive of a T2 tumor.\nAdditional staging features are as follows:\n\nTumor: Hemi-circumferential mass extending from 10 to 5 o'clock.\nDistance from anal verge (AV) (mm): 82\nExtends cranio-caudally (CC) (mm): 37\nDistal edge lies: 8.2 cm from verge\nUpper border lies: 11.9 cm from verge\n\nSTAGING\nInvading tumor edge: No definite transmural invasion\nMuscularis propria: From 10 to 1 o'clock 9.4 cm from the verge there is\nlikely involvement of muscularis propria but without transmural spread\nExtramural spread (mm): Not seen\nExtramural venous invasion (EMVI): Not seen\nPeritoneal reflection: uninvolved\nAdjacent pelvic organs (levator ani, prostate, vagina): uninvolved\n\nClosest CRM (Circumferential resection margin) at: 12 o'clock by 1.4 Cm\nClosest CRM to AV (anal verge) (mm): 1.5\n\nMinimum tumor distance to MRF: 1.4\n\nMesorectal lymph nodes - Size (mm): The most suspicious nodes include: A\nheterogeneous 11 x 6 mm node (series 7, image 2), and a round and slightly\nheterogeneous node measuring 6 mm (series 7, image 3) There are numerous\nadditional round lymph nodes measuring 4 mm or less which are indeterminate.\nMesorectal lymph nodes - heterogeneous signal: Yes, as above\nMesorectal lymph nodes - capsular irregularity: No\n\nPelvic side wall nodes: None\n\nOther Findings:\n\nThe prostate measures 4.0 x 2.8 x 4.5 cm corresponding to an estimated volume\nof 26 cc. The seminal vesicles are unremarkable. There is a 10 x 17 mm round\nT2 hyperintense lesion in the scrotum in keeping with a right epididymal cyst.\n\nThere is a small fat containing left inguinal hernia.\n\nAlong the left adductor musculature, there is a T2 hyperintense\nwell-circumscribed fusiform lesion with low level enhancement measuring 26 x 7\nmm (6:19, 2:4, 11:76, 4a:24). The lesion is bright on the high b value\nsequence and ADC map in keeping with T2 shine though.\n\nThe bone marrow demonstrates normal signal characteristics. No concerning\nosseous lesions.\n\nIMPRESSION: \n\n1. Known rectal cancer is identified as a 3.7 cm hemi-circumferential mass\nextending from 10 to 5 o'clock approximately 8.2 cm from the anal verge. \nThere is likely involvement of the muscularis propria and some spiculations\ncompatible with peritumoral fibrosis are seen, but there is no definite\nextramural extension of tumor. Findings are consistent with a T2 rectal tumor.\n\n2. Multiple nodes are seen in the mesorectal fat, of which two are suspicious\ndue to size and signal heterogeneity; additional numerous round lymph nodes\nmeasuring up to 4 mm are indeterminate. Findings are consistent with at least\nN1 disease.\n\n3. 0.7 x 2.6 cm fusiform lesion located along the hip adductor musculature on\nthe left is hyperintense on T2WI, well-circumscribed, and shows low level\nenhancement. This finding may represent a nerve sheath tumor or myxoid tumor.\n\n4. Benign right epididymal cyst.\n\nRECOMMENDATION(S): Suggest follow up of the likely nerve sheath tumor or\nmyxoid tumor along the left hip adductor musculature, with pelvic MR in 6\nmonths.\n",

treatment?\n\nTECHNIQUE: T1- and T2-weighted multiplanar images of the abdomen and pelvis\nwere acquired in a 3.0 T magnet.\nIntravenous contrast: 8 mL Gadavist.\n\nCOMPARISON: Multiple prior MRIs of the abdomen and pelvis. The most recent\nis from ___\n\nFINDINGS: \n\nLower thorax: Limited views of the lower thorax demonstrate no pleural\neffusion and no pericardial effusion.\n\nLiver:\n\nThe liver is normal in morphology and size. No significant loss of signal\nfrom in to out of phase imaging to suggest hepatic steatosis. There is mild\nedema in the fatty tissue of the upper abdomen including in the\nretroperitoneum, perihepatic region, porta hepatis and bilateral pericolic\ngutters without frank ascites.\n\nAs seen previously, the liver contains multiple T2 mildly hyperintense, rim\nenhancing lesions which demonstrate restricted diffusion compatible with\nmetastatic disease. These are scattered throughout both lobes of the liver. \nThe number of lesions is unchanged compared to the prior examination. They\nalso exhibit a similar degree of contrast enhancement and diffusion\nrestriction. There has been a diffuse slight increase in size of the lesions.\n\nFor example, a lesion in the dome segment 8, (1802:14) now measures 2.4 x 1.9\ncm, previously 1.6 x 1.5 cm. A lesion in segment 8 more inferiorly,\n(1802:33), measures 2.0 x 2.0 cm as compared with 1.6 x 1.6 cm. A lesion in\nthe superior aspect of segment 2 measures 1.6 x 1.2 cm, (1802:26) as compared\nwith 1.1 x 1.0 cm.\n\nThe hepatic veins are patent as is the portal venous system. Hepatic arterial\nvasculature is conventional.\n\nBiliary: No intra or extrahepatic bile duct dilation. The gallbladder is\nsurgically absent.\n\nPancreas: The pancreas retains its intrinsic T1 hyperintense signal. No focal\npancreatic lesion and no pancreatic ductal dilation.\n\nSpleen: The spleen is enlarged measuring 14 cm in craniocaudad dimension,\npreviously it measured 13 cm. There is no focal splenic lesion.\n\nAdrenal Glands: The bilateral adrenal glands are normal.\n\nKidneys: Both kidneys are symmetric in size and degree of contrast\nenhancement. There is an unchanged 2 cm parapelvic cyst in the left kidney.\n\nGastrointestinal Tract: The examination is not protocolled to assess the\nbowel. There is no evidence of bowel obstruction, wall thickening or abnormal\nenhancement. There is minimal diverticulosis of the sigmoid colon. A known\npolypoid lesion in the distal duodenum is not clearly visualized on today's\nexamination noting this area of bowel is decompressed.\n\nPelvis: Evaluation of the known rectal cancer is limited and the examination\nis not tailored to re-stage the rectal tumor. There does remain focal\nirregularity of the anterior left lateral rectal wall in the ___ o'clock\nposition. There is correlating restricted diffusion in this area as well. \nThe focal area of irregularity contacts the posterior aspect of left-sided\nperipheral zone, similar to prior\n\nThe bladder is mildly thick walled but unchanged. The prostate is enlarged.\n\nLymph Nodes: No pathologically enlarged adenopathy in the included\nfield-of-view.\n\nVasculature: Hepatic arterial anatomy is conventional. The abdominal aorta is\nnonaneurysmal. There is focal ectasia of the proximal celiac artery which\nmeasures 1.3 cm in diameter. This is unchanged across prior studies and there\nis no stenosis at the origin.\n\nOsseous and Soft Tissue Structures: Degenerative changes of the endplates of\nthe lumbar spine. The osseous marrow signal is diffusely decreased on T2 and\nincreased on DWI sequences compatible with red marrow.\n\nIMPRESSION: \n\n1. Numerous hepatic metastases are increased in size but unchanged in number\ncompared to the prior examination from ___.\n\n2. Splenomegaly which is new relative to 3 months ago.\n\n3.

1\nmg of intramuscular glucagon was administered to reduce bowel peristalsis.\n\nMultiplanar 2D and 3D reformations and subtraction images were generated on an\nindependent workstation.\n\nNo previous for comparison.\n\nFINDINGS:\n\nThere is a broad-based, sessile lesion approximately 6.7 cm from the anal\nverge. It extends from approximately 11 o'clock to 8 o'clock (with reference\nto the dorsal lithotomy position), occupying 75% of the rectal circumference\nat this level. At its thickest portion, it measures approximately 1 cm in\nthickness. There is suspicion of extramural extension of the tumor, best seen\non reformatted images (630:30) from 3 o'clock to 5 o'clock, with lobulated\nenhancing mass extending to the mesorectal fat with linear enhancing\nspiculations. Assessment of these findings is mainly based on the\npost-contrast images as the axial T2-weighted images obtained perpendicular to\nthe rectum at the level of the tumor, are degraded by peristalsis and motion\nartifact. The closest distance of enhancing tumor to mesorectal fascia is\napproximately 5 mm (630:30) in the left posterolateral aspect, although there\nis milder enhancement between this portion of tumor and the mesorectal fascia\nwhich may be due to desmoplastic reaction, although presence of some tumor\ncells within this region cannot be excluded by MR. ___ slight retraction of\nthe mesorectal fascia here is compatible with effects of local desmoplastic\nreaction.\n\nAnteriorly, there is also irregularity and bulge at 12 to 1 o'clock position\nof the tumor without clear extramural spread. There is no invasion of\nperitoneum in this location. There is a clear fat plane between the tumor and\nseminal vesicles. \n\nThere is a 5-mm heterogeneously enhancing left internal iliac chain lymph node\nwith heterogenous enhancement and slightly irregular morphology on T2WI, for\nwhich metastatic involvement cannot be excluded. \n\nThere is no peritoneal free fluid or nodularity. Visualized portion of bony\npelvis, bladder, seminal vesicles and prostate are unremarkable.\n\nPosterolateral to the coccyx in the subcutaneous fat, there is a 15 mm\nteardrop shaped fluid-containing structure with progressive rim enhancement,\nlikely representing a subcutaneous sebaceous cyst with infectious or\ninflammatory change versus a pilonidal cyst. The adjacent bone does not\ndemonstrate any abnormal enhancement. Clinical correlation is recommended.\n\nMultiplanar 2D and 3D reformations and subtraction images generated multiple\nperspectives for the dynamic series (630).\n\nIMPRESSION:\n\nCarpet-like rectal mass located 6.7 cm from anal verge with extramural\nextension, MRI stage T3. Circumferential resection margin 5 mm\nposterolaterally; mild enhancement extends to the CRM which may represent\ndesmoplastic reaction, although extension of tumor cells to the mesorectal\nfascia

On\nthe sagittal images, it has the appearance of an annular mass with mild\nluminal narrowing. On orthogonal images, it involves primarily the right wall\nwith extension to the anterior and posterior walls of the rectum. It measures\nup to 1 cm in width and 5.3 cm in length. There is desmoplastic reaction\naround the rectal mass and there are small linear areas of extension from the\nrectal mass into the perirectal fat. The periteoneal reflection is difficult\nto ascertain in this patient. The mass appears to involve the anterior\nmesorectal fascia/peritoneal reflection (4:15) which is focally thickened and\ntethered in this region. No intraperitoneal extension is identified. Post-\ncontrast images are limited by motion artifact. Findings are compatible with\npatient's history of rectal adenocarcinoma.\n\nThere are at least four subcentimeter perirectal nodes such as a 5-mm node in\nthe right perirectal fat seen on series 4, image 16. No bulky external or\ncommon iliac adenopathy. Hyperplasia of the inner gland of the prostate with\nprotrusion into the bladder base. Remainder of the visualized viscera are\nunremarkable. 4-mm right external iliac node.\n\nMultiplanar 2D and 3D reformations delineated the dynamic series with multiple\nperspectives.\n\nIMPRESSION:\nRectal mass with apparent extension beyond the muscularis propria and\ninvolvement of the anterior mesorectal fascia/peritoneal reflection. Multiple\nsubcentimeter perirectal nodes. MR findings suggestive of at least a stage T3\ntumor.\n\n", "rows": [ { "field": "Age", "GPT 5.5 Output": "not mentioned", "GPT Output, modified by Annotator Radiologist where necessary": "not

seed\nplacement dated ___.\n\nFINDINGS: \n\nLower thorax: History assessment, but grossly clear.\n\nLiver: There is minimal drop of signal on the T1 out of phase images compared\nwith in phase images, consistent with minimal steatosis. There is no\nsuspicious focal hepatic lesion.\n\nBiliary: There is no intra or extrahepatic biliary ductal dilation. The\ngallbladder has a thin wall without evidence of edema. There is no\ngallbladder or biliary duct stones.\n\nPancreas: The pancreas is somewhat atrophic, particularly in the region of the\npancreatic body. There is no significant ductal dilation or solid mass lesion\nidentified.\n\nSpleen: Not enlarged, without focal abnormality.\n\nAdrenal Glands: No discrete nodularity of either the right or left adrenal\ngland.\n\nKidneys: Left kidney appears to be surgically absent. Right kidney\ndemonstrates homogeneous enhancement. 9 mm low right upper pole renal cyst\nand 4 mm right lower pole renal cyst (series 4, images 29, 41).\n\nGastrointestinal Tract: No abnormal dilation of small or large bowel loops. \nColonic diverticula noted.\n\nPelvis: Uterus is nonvisualized, post hysterectomy.\n\nLymph Nodes: No mesenteric, retroperitoneal, or pelvic lymphadenopathy is\npresent.

Stage T3N1 by EUS. // Restaging. ****RECTAL CANCER PROTOCOL***\n\nTECHNIQUE: T1- and T2-weighted multiplanar images of the pelvis were acquired\nin a 1.5 T magnet.\nIntravenous contrast: 9 mL Gadavist\n\nCOMPARISON: None.\n\nFINDINGS: \n\nThere is T2 hypointense wall thickening of the rectum extending from the 11 to\nthe 5 o'clock position in the region of the tumor, compatible with post\nradiation change.\n\nA shouldering lesion with diffusion restriction is seen in the rectum, with\nlower margin 6.5 cm above the anal verge. The lesion extends over a distance\nof 4.7 cm, and spans between the 12 and 4 o'clock position. There is\nhomogeneous enhancement at this level which extends into the muscularis\npropria. There is no definite extension beyond the wall, however there is a\nquestionable millimetric bulge noted at the 2 o'clock position (10:41). Focal\nextension beyond the rectal wall at this site and stage T3 disease is\ndifficult to exclude.\n\nIn addition, there are T2 hypointense spiculations noted in the meso rectal\nfat at this level, suggestive of post treatment or reactive desmoplastic\nchange.\n\nThere is no suspicious lymphadenopathy. Although there are many vessels\ncoursing in the region of the described infiltrative/desmoplastic changes,\nthere is no definite evidence of extra mural vascular invasion.\n\nTumor regression grade cannot be evaluated as we do not have access to the\nprior, pretreatment study.\n\nNo suspicious bony lesions.\n\nThe bladder and visualize prostate are unremarkable.\n\nRemainder of the partially visualized bowel loops are within normal limits.\n\nIMPRESSION: \n\nRectal lesion involving the muscularis propria between the 12 and 4 o'clock\nwith lower margin arising 6.5 cm above the anal verge and extending over a\ndistance of 4.7 cm without suspicious lymphadenopathy or evidence of extra\nmural vascular invasion. There is a tiny focal bulge seen at the 2 o'clock\nposition (10:41), with possible minimal residual extension beyond the rectal\nwall. Overall the post treatment PE stage is T2/ early T3. No evidence for\nlymphadenopathy.\n\nLow intensity spiculations noted in this area are likely sequelae of post\ntreatment change.\n\nTumor regression stage cannot be evaluated as the prior imaging is available\nfor comparison.

and T2-weighted multiplanar images of the abdomen and pelvis\nwere acquired in a 1.5 T magnet.\nIntravenous contrast: 7 mL Gadavist.\n\nCOMPARISON: CT abdomen pelvis: ___.\n\nFINDINGS: \n\nRECTUM AND INTRAPELVIC BOWEL: A polypoidal mass in the rectosigmoid has the\nappearance of a villous adenoma with intussuscepted stalk and demonstrates\nwall puckering at the stalk attachment site (04:15, 05:18).\n\nTumor: Polypoidal\nDistance from anal verge (AV) (cm): 13.7.\nExtends cranio-caudally (CC) (cm): 4.4 cm.\nDistal edge lies: 9 cm above puborectalis sling\nUpper border lies: At the peritoneal reflection\n\nSTAGING\nInvading tumor edge: The mass is confined within the muscularis propria which\nis well-defined. Slight wall puckering at the site of the stalk attachment is\nnoted (05:18).\nMuscularis propria: confined to\nExtramural spread (mm): None\nExtramural venous invasion (EMVI): None.\nPeritoneal reflection: None\nAdjacent pelvic organs ___, prostate, vagina): None.\n\n\n\nMesorectal lymph nodes - Size (mm): >5mm\nMesorectal lymph nodes - location: A 7 mm presacral lymph node (11:2), 5 mm\npresacral lymph node (11:23). There is also a 4 mm posterior perirectal lymph\nnode (11:13)\nMesorectal lymph nodes - heterogeneous signal: no\nMesorectal lymph nodes - capsular irregularity: no\nMesorectal lymph nodes: If malignancy is present, these findings represent N1\n(< 4) disease. Otherwise, these lymph nodes are likely reactive.\n\nPelvic side wall nodes: yes\nIf Yes to Pelvic side wall nodes (location): Left\nIf Yes to Pelvic side wall nodes (type): Likely reactive\n\n\nStaging Assessment: Likely rectosigmoid villous adenoma.

the\nuneventful intravenous administration of 7 mL of Gadovist. In addition, 60 cc\nof barium sulfate administered per rectum and 1 mg of intramuscular glucagon\nwas given to reduce bowel motion.\n\nFINDINGS: \n\nThe exact location of the previously described polypectomy is not apparent\nfrom the imaging or the endoscopy report; however, there is some region of\nabnormal signal intensity and mucosal thickening noted along the anterior wall\nof the upper rectum (series 3, image 15) extending over a distance of\napproximately 2 cm. This arises approximately 14 cm from the anal verge and\nextends craniocaudally for 2 cm and is approximately 1.5 cm just distal to the\nrectosigmoid junction (series 3, image 15). This area of irregularity is\nconfined to the mucosa and submucosa. The muscularis propria is identified and\nintact (series 3, image 16).

No endoluminal lesion is identified and no additional polyps\nare seen. Evaluation of the meso-rectal fascia demonstrates no abnormally or\npathologically enlarged lymph nodes. \n\nThere is no pelvic adenopathy or free fluid. Note is made of a 7-mm right\nexternal iliac lymph node (series 439) which contains fat and is likely benign\nin origin and is not pathologically enlarged.

on a 1.5\nTesla magnet including dynamic 3D imaging obtained prior to, during, and after\nthe uneventful intravenous administration of 0.1 mmol/kg (5 mL) of Gadavist.\n\nCOMPARISON: CT abdomen and pelvis ___.\n\nFINDINGS:\n\nThere are multiple dilated fluid-filled loops of small bowel in the pelvis,\nthe largest measures approximately 3.5 cm in maximal diameter, and there are\nmultiple air-fluid levels. This is better assessed on the recent CT. The\npatient appears to have had a supracervical hysterectomy or the uterus may be\nsomewhat atrophic. The ovaries are not clearly seen. \n\nThere is mild dilatation of the left ureter (3:24) down to the level of the\nroof of the acetabulum, at which point there is no obstructing mass lesion\nseen; however, the lumen is obscured with hyperenhancement of the wall of the\nureter. The appearances are more suggestive of a stricture rather than\nextrinsic compression of the distal left ureter. There is relatively\nprominent periureteric venous plexus at this level, which does make assessment\ndifficult. \n\nThere is marked edema of the piriformis muscles bilaterally, presumed to be\nrelated to prior radiotherapy. In addition, there is abnormally high signal\nintensity on T2-weighted images within the left side of the sacrum. On\nseveral images, there is a linear low signal intensity line passing through\nthis area, the appearances are most suggestive of a sacral insufficiency\nfracture. No pelvic lymphadenopathy.\n\nIMPRESSION:\n\n1. Mild left hydroureter with transition at an apparent stricture in the\ndistal 2 cm of the ureter. No extrinsic mass compression can be identified.\n2. Edema of the piriformis muscles bilaterally, thought to be related to\nprior radiotherapy.\n3.

In addition, there is ill-defined\nincreased T2 signal within the piriformis muscles bilaterally, likely related\nto post radiation changes or early atrophy. Urinary bladder, vagina, and\nurethra are unremarkable. Uterus shows no abnormalities. Ovaries are\nunremarkable bilaterally.\n\nMultiplanar reformations and subtraction images provided multiple perspectives\nfor the dynamic series.\n\nIMPRESSION:\n\n1. Linear region of increased T2 signal and enhancement with associated dark\nsignal intensity foci in the right perirectal region extending laterally from\na loop of bowel as well as presacral enhancement right pelvic wall enhancement\nand probable susceptibility (air), which together are highly suspicious for a\nleak. It is unclear whether this is arising from the anastomosis or more\nproximally from rectal wall breakdown. A dedicated fluoroscopic examination\nis suggested for further evaluation.\n\n2. No definite evidence of recurrent or residual disease.\n\n3. Nonspecific, enlarged left perirectal lymph node which may be followed on\nsubsequent followup imaging.\n\nThe referring clinician, Dr. ___ was informed of these results at\n4:30 p.m, ___.\n\n",

after\nthe uneventful intravenous administration of 18 mL of Magnevist.\n\nMultiplanar 2D and 3D reformations and subtraction images were generated on an\nindependent workstation.\n\nFINDINGS:\n\nThe postoperative surgical bed is unremarkable in appearance. There is no\nevidence of soft tissue/enhancing soft tissue to suggest residual or recurrent\ndisease. There is minimal linear enhancement identified posterior to the\nprostate gland which is likely related to patient's history of radiation\ntherapy for prostate carcinoma. The seminal vesicles are visualized and are\nunremarkable in appearance.\n\nThere are irregular areas of T1 and T2 hypointense signal within intense\ncontrast enhancement identified low in the subcutaneous tissues of the buttock\narea, posteriorly which abuts the skin surface near the gluteal fold. This is\nfelt to be most likely related to postoperative changes and less likely tumor\nrecurrence given that the primary tumor was rectal (and thus at distance from\nthis area) in nature. Although this study was not performed as a perianal\nfistula study, no fistula is identified.\n\nOf note, there is amorphous area of T2 hypointense signal with a few foci of\nT2 hyperintensity noted within the retroperitoneal region extending into the\npresacral region between the common iliac arteries. These are not evaluated\non the dynamic series, as the images were not obtained high enough given the\nrectal protocol.\n\nNo free fluid within the pelvis. No evidence of abnormal pelvic\nlymphadenopathy is identified.\n\nMultiplanar 2D and 3D reformations provided multiple perspectives for the\ndynamic series, including sequences, 648.\n\nIMPRESSION:\n1. No definite recurrence within the postoperative bed.\n\n2. T1 and T2 hypointense signal intensity with intense post-contrast\nenhancement low and posteriorly within the subcutaneous tissues abutting the\nskin surface near the gluteal fold. These findings are most likely secondary\nto post-operative changes, and less likely to represent tumor recurrence given\nthat the primary tumor was a rectal tumor and given patient's postoperative\ncomplications as per CareWeb.\n\n3. Post-radiation changes posterior to the prostate gland.\n\n4. Amorphous T2 hypointense signal within the retroperitoneal region\nextending into the upper pelvis/presacral area between the common iliac\narteries.

T2-weighted images were obtained through the\npelvis before and then after the uneventful administration of 0.1 mmol/kg (20\nmL) of gadolinium-DTPA. 150 mL of 4:1 of Redicat/Gastromark was administered\nrectally and then removed prior to scanning. \n\nMultiplanar 2D and 3D reformats as well as subtraction images were generated\non an independent workstation.\n\nFINDINGS: \n2.5 x 1.4 cm rectal mass (200:56) located 3 cm from the anorectal junction and\n8.5 cm from the anal orifice extends approximately 90 degrees of the rectal\ncircumference from 12 o'clock to 3 o'clock in the supine position (left\nanterior wall). This mass extends focally beyond the muscularis propria into\nthe fat and extends greater than 5 mm outside the muscularis propria directly\nand roughly to 1 cm from the mesorectal fascia left lateral. There is focal\ndilation and intermediate signal intensity on all sequences (100:52) in a left\nperirectal vein which hypoenhances centrally, consistent with extramural\nvenous invasion. There appear to extensions into smaller veins at the left\naspect of the tumor at the junction of muscularis propria and mesorectal fat. \nOne adjacent left perirectal lymph node measuring 7 mm (100:29) lies 3 mm from\nthe mesorectal fascia, demonstrates irregular margins. A second lymph node\nmeasuring 4 mm at the level of the lower sigmoid colon demonstrates slightly\nirregular margins and has heterogeneous enhancement (100:5). No definite\nabnormal internal iliac or pelvic sidewall lymph nodes. The seminal vesicles\nand bladder are unremarkable. The prostate demonstrates predominantly\nhomogeneous intermediate signal intensity on T2 weighted images consistent\nwith prior radiotherapy. Although this exam was not tailored for evaluation\nof the prostate there is no definite intraglandular tumor or extraprostatic\ndisease. A fat containing left inguinal hernia is noted. \n\n2D and 3D reformats were essential in evaluating the tumor and nodes.\n\nIMPRESSION:\n\n1. Stage T3 N1 rectal adenocarcinoma with extramural vascular invasion of a\nleft perirectal vein and 2 abnormal perirectal lymph nodes. \n\n2. Fat containing left inguinal hernia. \n\n3. Post therapy changes in the prostate. No definite prostate cancer seen\nthough this study was not tailored to evaluate for prostate cancer.\n\nFindings were discussed in person with Dr. ___ at the time of\ndictation.\n", "rows": [ {

The inferior-most aspect is approximately 6 cm\nabove the anal verge with T2 hypointense, heterogeneously enhancing tumor\nreplacing the normal anterior and left lateral rectal wall. There is\ntransmural disease, with extension both intraluminal and extensive solid mass\nextending exophytically within perirectal fat towards the left pelvic wall and\nsuperiorly. Perpendicular to the plane of the rectum, the tumor extends at\nleast 5.7cm beyond the muscularis propria and involves the mesorectal fascia\nalong the posterolateral aspect on left, seen for example on series 6, image\n23. Direct spread of tumor is seen extending superiorly along the inferior\nmesenteric vessels, at least to the level of the bifurcation of common iliacs\ninto the internal and external iliacs, a length of at least 15cm. There may be\nsubtle extension to the level of the aortic bifurcation. Field of view of\nimaging the pelvis does not allow for assessment more superiorly into the\nabdomen. Superior extent can be best visualized on sagittal series 3, images\n13 and 14.\n\nTwo nodules are seen within the presacral space (6:31) with identical signal\nand enhancement characteristics, representing either foci of nodal involvement\nor implants. Otherwise no lymphadenopathy is seen.\n\nThere is heterogeneity of the lower lumbar and sacral bone marrow (9:67, 6:6),\nincompletely evaluated on this examination. Osseous metastatic disease is not\nexcluded.\n\nNo ascites.\n\nPelvic vessels are patent without thrombus.\n\nIMPRESSION: \n\n1. Transmural rectal tumor with extension to and involvement of the\nmesorectal fascia posterolaterally on the left, and at least 15cm of superior\nextension along the inferior mesenteric vasculature. Inferior most margin is\n6cm from the anal verge. Though there is broad contact the mesorectal fascia,\ntumor is not overtly through the peritoneal reflection.\n2.

T2-weighted MR images were acquired on a 1.5\nTesla magnet including dynamic 3D imaging obtained prior to, during, and after\nthe uneventful intravenous administration of 18 mL of Magnevist. A rectal\ntube was inserted and approximately 150 mL of barium solution was administered\nwithout complication. 1 mg of intramuscular glucagon was administered to\nrestrict bowel motion.\n\nMultiplanar reformations and subtraction images were generated on an\nindependent workstation.\n\nFINDINGS:\nThere is a nonspecific, mildly enlarged 6-mm left iliac lymph node. There is a\nheterogeneous, large ulcerated enhancing rectal mass involving greater than\n75% of the circumference of the rectum and extends from approximately 4.5 cm\nproximal to the anal orifice. The attachment point of the mass is 6.5 cm\nproximal to anal orifice and 3.5 cm from anorectal junction. The mass measures\nmaximally to 1.7 cm in thickness. There is evidence of mesorectal fat invasion\nalong the left lateral aspect (sequence 6, image 17) and an irregular region\nof tethering and likely fibrotic reaction anteriorly. This region touches the\nmesorectal fascia, but appears to be desmoplastic reaction rather than tumor.\nThere are multiple surrounding, enlarged perirectal lymph nodes, the largest\nof which measures approximately 6 mm. There is an enlarged left posterolateral\nmesorectal lymph node that is approximately 1 mm from the mesorectal fascia\n(sequence 6, image 6). In addition, there is enlarged 11 x 7-mm left internal\nobturator lymph node.\n\nIn the presacral region, there is an ill-defined T2 hyperintense region of\nmass-like enhancement that causes anterior bowing of the mesorectal fascia.\nThere are vessels traversing this region and it demonstrates progressive\nenhancement on dynamic post-gadolinium sequences. There is an ill-defined area\nof increased T2 signal and mild enhancement in the left ilium, adjacent to the\nleft sacroiliac joint (sequence 100, image 46). Remainder of the visualized\nosseous structures show no abnormal marrow signal. Visualized urinary bladder\nand penis show no abnormalities. Prostate and seminal vesicles show no gross\nabnormalities. Mesenteric vasculature is unremarkable.\n\nMultiplanar 2D and 3D reformations and subtraction images provided multiple\nperspectives for the dynamic series.\n\nIMPRESSION:\nMRI STAGE: T3N2.\n1. Circumferential, irregular enhancing rectal mass consistent with\ncarcinoma, that has invasion into the mesorectal fat. Fibrotic-appearing\ntissue touches the mesorectal fascia anteriorly, but this is felt more likely\nto be desmoplastic reaction than tumor, though the latter can not be\ncompletely excluded. Exact CRM of the primary tumor is hard to define but is\nmore likely 5 mm.\n2. Multiple enlarged mesorectal lymph nodes, some of which are 1 mm from the\nmesorectal fascia (CRM = 1 mm).\n3. Nonspecific ill-defined area of abnormal signal and enhancement in the\nleft ilium with an appearance that is atypical for metastasis. Suggest further\nevaluation with a dedicated bony pelvis MRI for further characterization.\n4. Ill-defined region of abnormal signal and enhancement in the presacral\nregion that is of uncertain etiology that does not definitely exhibit\nmass-like characteristics and may represent a lymphatic malformation. Follow\nup MRI is suggested subsequent to pre-surgical treatment that the patient\nreceives.\n", "rows": [ { "field": "Age", "GPT 5.5 Output": "not mentioned", "GPT Output, modified by Annotator

"report_id": "15987101-RR-4", "report": "HISTORY: A ___ woman with lower rectal carcinoma by biopsy, location\nand size of tumor.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted images were acquired on a 1.5\nTesla magnet including dynamic 3D imaging obtained prior to, during, and after\nthe uneventful intravenous administration of 0.1 mmol/kg (18 mL) of\ngadolinium-DTPA.\n\nIn addition, approximately 100 mL of rectal barium was administered to distend\nthe rectum. 1 mg of glucagon was administered to reduce bowel motion.\n\nFINDINGS:\n\nThere is a low rectal tumor arising approximately 4 cm from the anal verge. \nThis enhancing tumor is a very heterogenous in signal intensity with\nrelatively large pockets that are T2 hyperintense suggesting mucin. This make\nassessment of tumor extent rather difficult as these T2 hyperintense areas\nappear as well-circumscribed locules which distort the muscularis propria, but\ndo not clearly penetrate through it (5:15). There is loss of the fat plane\nbetween the rectal mass and the left levator ani/puborectalis muscle (5:13)\nwith associated hyperenhancement in this region post-contrast (10:31). This\nmay be due to reactive inflammation within the muscle rather than frank tumor\ninvasion as the muscularis does appear to be intact in this region. The tumor\nextends in a craniocaudal direction for approximately 8 cm. The inferior\nmargin of the tumor closely approximates the superior aspect of the internal\nsphincter. In fact, some enhancing tissue appears to extend into the\nintersphincteric space (1050:31). \n\nNo perirectal lymph nodes are seen. \n\nThe patient has had a prior hysterectomy and adjacent to the left side of the\nvaginal cuff, there is a 2.5 x 1.4 cm soft tissue nodule. This is moderately\nhypointense on T2-weighted images and the appearance in proximity to the\nvaginal cuff suggests this may be postoperative scarring or residual ovarian\ntissue; however, a tumor deposit cannot be definitively excluded. Of note,\nhowever, the signal characteristics of this soft tissue is very different than\nthe primary tumor. \n\nNo pelvic sidewall lymphadenopathy. There is a 6-mm oval lymph node in the\npresacral space (5:35) without particularly concerning features. Moderate\nsigmoid diverticulosis. The bladder wall is mildly trabeculated, but\notherwise unremarkable. The visualized osseous structures are unremarkable.\n\nIMPRESSION:\n\n1. Low rectal tumor arising approximately 4 cm from the anal verge with the\ninferior margin approaching the internal sphincter and probably extending into\nthe intersphincteric space. This extends superiorly over a distance of 5 cm. \nNo definite extension into the perirectal fat; however, there is loss of the\nthin fat plane between the lower aspect of the tumor and the left levator\nani/puborectalis muscle with hyperenhancement which may be due to inflammatory\nchange rather than tumor involvement although this cannot be definitely\nexcluded. Probable T2 disease.\n\n2. No concerning lymph nodes seen.\n\n3. A 1.4 x 2.5-cm soft tissue nodule at the left side of the vaginal cuff\ncould reflect postoperative scarring versus residual ovarian tissue versus\ntumor deposit, the latter is considered less likely.\n\n4. Sigmoid diverticulosis.\n\n5.

No pericardial effusion.\n\nLiver: The liver contour is smooth. There is normal parenchymal signal\nintensity. No evidence of hepatic steatosis. Few punctate T2\nhyperintensities throughout the liver are again seen and likely represent\nbiliary hamartomas.\n\nSimilar size of ablation cavity at the border of segments VII/VIII measuring\nup to 1.8 cm, previously up to 1.8 cm in ___ and 2.4 cm in ___. \nAssociated hyperintense T1 signal appears more confluent, compatible with\nevolving coagulation necrosis. Linear enhancement around the periphery is\nfelt to represent adjacent vasculature. No findings suggestive of recurrent\ndisease.\n\nIn the inferior tip of segment VI, there is a new 1.0 cm arterially\nhyperenhancing lesion (2401:100), which demonstrates washout and capsular\nenhancement (2403:101) in subsequent phases, is somewhat atypical but\nconcerning for metastasis. Within segments V and VIII, additional\nhypoenhancing lesions measuring 0.9 cm (2402:105) and 1.0 cm (2402:31) which\npossibly hyperenhancing in the arterial phase are also new and concerning for\nmetastasis.\n\n6 mm hypoenhancing lesion within segment VI (___:68) is unchanged. 4 mm\nhyperenhancing lesion (series 2402, image 30) is unchanged. Attention on\nfollow-up.\n\nA subcentimeter arterially hyperenhancing lesion without correlates on\nsubsequent phases or other sequences within segment VII (2401:44) likely\nrepresents transient hepatic intensity difference.\n\nBiliary: The gallbladder contains a large amount of stones and/or inspissated\nbile. No abnormal wall thickening or pericholecystic fluid. No intrahepatic\nbiliary ductal dilatation. Borderline dilation of the common bile duct\nmeasuring 1.1 cm is unchanged since ___. An apparent tiny filling defect\nwithin the dependent portion of the distal common bile duct (12:28) likely\nrepresents nonobstructing stone/sludge.\n\nPancreas: There is normal intrinsic T1 signal. No suspicious lesion. The\nmain duct is normal in caliber.\n\nSpleen: Normal in size. No suspicious lesion.\n\nAdrenal Glands: Normal in size and shape bilaterally.

Multiple bilateral cortical and parapelvic cysts appear similar,\nincluding hemorrhagic or proteinaceous cysts within the left kidney measuring\nup to 0.7 cm (22:73, 87). No suspicious lesions are seen.\n\nGastrointestinal Tract: Status post small bowel resection with end ileostomy\nand subsequent take down. Wall thickening of small bowel loops within the\npelvis likely represents radiation enteritis. There are scattered colonic\ndiverticula without evidence of acute diverticulitis.\n\nPelvis: Few small bladder diverticula are again seen. The distal ureters are\nunremarkable. A moderate right hydrocele is partially visualized (2501:69).\n\nRectal tumor assessment is suboptimal due to marked motion artifact as well as\nartifact rendering the diffusion-weighted imaging

One-month\nhistory of low back pain.\n\nNo prior imaging is available for direct comparison.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted images were acquired on a 3 Tesla\nmagnet including dynamic 3D imaging, obtained prior to, during and after the\nuneventful intravenous administration of 0.1 mmol/kg (15 cc) of\ngadolinium-DTPA. Additionally, 1 mg of glucagon was administered\nintramuscularly to reduce bowel motion. Diffusion imaging was acquired.\nSubtraction imaging was also generated and reviewed.\n\nFINDINGS:\n\nApproximately 11 cm from the anal verge, a circumferential but eccentric T2\nhypointense progressively enhancing mass is seen measuring 4.4 x 2.1 cm\n(series 3A, image 16) consistent with newly discovered neoplasm. Given\nmotion-related artifacts in this region, local staging of the mass is limited.\nThe mesorectal fascia is within 1 mm of the right lateral and superior aspect\nof the mass. There are multiple regional lymph nodes with rim enhancement\nsuggesting central necrosis. Specifically, medial to the mass on the axial\nimaging (series 1001, image 70), a necrotic lymph node is seen measuring 5 mm.\nAdditional adjacent lymph nodes are also seen measuring up to 5 mm. More\nanterolateral and inferior within the mesorectal fat on the right side (series\n1001, image 46), a necrotic lymph node is present measuring 8 mm. On series\n1001, images 65-70, there are thin spiculations arising from the mass on the\nleft lateral aspect likely representing desmoplastic reaction without definite\nextension into the mesorectal fat. Engorged vessels at this level are\nintimately related to the mass and may be indicative of lymphovascular\ninvasion. There is circumferential wall thickening involving the rectosigmoid\ncolon proximal to the large irregular mass. This may represent\npost-procedural changes or ischemia related to the mass. There are external\niliac chain lymph nodes measuring up to 4 mm in short axis. Subcentimeter\nbilateral inguinal lymph nodes are seen, not pathologically enlarged. \n\nThe visualized small bowel loops in the pelvis are normal in caliber. The\npelvic arteries and veins are patent. Urinary bladder is distended without\nfocal abnormality.

multiplanar images of the abdomen and pelvis\nwere acquired in a 1.5 T magnet.\nIntravenous contrast: 6 mL Gadavist.\n\nCOMPARISON: MR abdomen pelvis dated ___, PET-CT dated ___.\n\nFINDINGS: \n\nPlease note that this study is limited due to patient motion artifact.\n\nLower thorax: Lung bases are grossly clear. Please refer to the CT chest\nperformed on the same day for full detail of intrathoracic findings.\n\nLiver: Postsurgical changes related to prior segment VIII segmentectomy are\nagain seen. A heterogeneous subcapsular collection adjacent to the surgical\nbed is again noted measuring approximately 3.1 x 3.1 cm (5:7) which has\ndecreased in size from prior, and likely represents a seroma. No suspicious\nhepatic lesions are identified.\n\nBiliary: The gallbladder surgically absent. There is no intra or extrahepatic\nbiliary ductal dilatation.\n\nPancreas: Pancreas demonstrates homogeneous signal intensity and morphology. \nNo focal pancreatic lesions, pancreatic ductal dilatation, or peripancreatic\nstranding identified.\n\nSpleen: Spleen is normal in size. Again seen is a rim of low signal intensity\nperipherally around the spleen, likely hemosiderin deposition. No focal\nsplenic lesion identified.\n\nAdrenal Glands: The adrenal glands are normal in size and shape.\n\nKidneys: Multiple T2 hyperintense simple cysts are seen in the bilateral\nkidneys. No evidence of hydronephrosis, enhancing renal lesions, or\nperinephric abnormality.\n\nGastrointestinal Tract: Imaged loops of large and small bowel appear grossly\nunremarkable.\n\nPelvis: Prostate gland is enlarged, as seen before. No pelvic sidewall or\ninguinal lymphadenopathy. There is small volume ascites.\n\nLymph Nodes: No enlarged mesenteric or retroperitoneal lymphadenopathy. No\nomental nodularity is seen within the limitations of this slightly motion\ndegraded study.\n\nVasculature: The abdominal aorta is normal in caliber. Portal and hepatic\nveins are patent.\n\nOsseous and Soft Tissue Structures: No suspicious osseous lesions are\nidentified.\n\nIMPRESSION: \n\nThis study is limited by extensive motion artifacts.\n\n1. Within the limitations of this study, no omental nodules are detected.\n2. Interval decrease in size of postoperative fluid collection at the segment\nVIII resection site.\n3. No new hepatic lesion.

NO glucagon was administered.\n\nFINDINGS: \nThe quality of this study is suboptimal secondary to motion artifact due to\nbreathing and bowel peristalsis, in the abscence of glucagon.\n\nA hemicircumferential tumor, has its distal margin slightly greater than 12 cm\nfrom the anal orifice and extends for slightly more than 3 cm proximally. \nThere is loss of a fat plane between the tumor and the uterine fundus, however\nwithout definite invasion. The relationship of uterus and tumor appears to\nhave changed compared to prior CT, suggesting lack of adherence. The tumor\nextends through the rectal wall to the right anteriorly and appearsto extend\ninto the perirectal fat. There is an irregular enhancing nodular focus in\napparent contiguity, which may represent tumor deposit versus metastatic lymph\nnode. Other small presacral and external iliac nodes are seen which are\nsmaller that 5 mm and with homogenous signal intensity. \n\nEvaluation of the adnexal region demonstrates a simple cyst within the left\novary, measuring 3 x 2.2 cm and a smaller cyst within the right ovary. Uterus\notherwise is unremarkable.\n\nThere is no free fluid. There is no ascites. There are no suspicious osseous\nlesions.\n\n\nIMPRESSION: \n3.2 cm, hemicircumferential, upper rectal tumor appears to extend through the\nrectal wall into adjacent fat, consistent with a T3 tumor.

These lesions\nuniformly enhance and are highly suspicious for malignancy, corresponding with\nareas of FDG avidity on the recent outside hospital PET-CT. The largest lumbar\nspine lesion is located within L4 measuring up to 1.9 x 1.6 cm (3:1). The\nlargest lesion in the pelvis is located in the posterior aspect of the left\niliac wing measuring up to 2.3 x 1.6 cm (3:9). Multiple additional lumbar\nspine, sacral, iliac, and femoral neck, lesions are identified as well (3: 5,\n7, 11, 13, 16, 37, 41). A T2 hyperintense lesion in the right femoral\ndiaphysis is only visualized on the sagittal STIR sequence, and not included\nin its entirety (5: 55).\n\nThere is no evidence of avascular necrosis, fracture, stress fracture. There\nis normal signal at the sacroiliac joints, without evidence of sacroiliitis.\n\nThe patient is status post rectal resection with diverting colostomy. A large\nfat containing parastomal hernia is unchanged from prior studies. There is\nuniform mild bladder wall thickening, potentially attributable to prior\nradiation therapy or chronic outlet obstruction. Small cysts noted in the\nleft and question right seminal vesicle (03:30).\n\nIMPRESSION:\n\n\n1. Multiple enhancing masses throughout the bones of the pelvis, proximal\nfemurs, and visualized lumbar spine corresponding to the areas of FDG avidity\non the outside hospital PET-CT and highly suspicious for malignancy. In the\nsetting of known rectal cancer, these likely represent metastatic lesions,\nthough the imaging appearance itself is non-specific.\n2.

Staging.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted sequences were acquired on a 1.5\nTesla magnet according to rectal mass protocol. Three T1-weighted sequences\nwere acquired prior to, during and after the uneventful administration of 0.1\nmmol/kg (20 cc) of gadolinium-DTPA. Multiplanar subtraction images and\nreformations were carried out on an independent workstation. The examination\nwas performed after instillation of rectal contrast (a mixture of GastroMARK\nand barium).\n\nCOMPARISON: Ultrasound rectum ___.\n\nFINDINGS:\n\nThere is a mass involving the middle and lower one-third of the rectum. The\nmass measures a maximum of 4.1 cm in craniocaudal extent. It extends to the\nanorectal junction. The mass is almost circumferentially involving the mid to\ndistal rectum. There is relative sparing of a small segment between 6 and 8\no'clock with the tumor epicenter anterior and to the left, most bulky between\n11 and 3 o'clock. In the anterior and left anterolateral aspect of the\ninvolved rectal segment, there is evidence of bulky transmural extension of\nthe rectal tumor into the perirectal fat. This is compatible with T3 tumor\nstage. \n\nThe tumor extends significantly in the anterior direction to abut the anterior\naspect of the mesorectal fascia. The mass also abuts but does not clearly\ninvade the posterior aspect of the seminal vesicles. Note is made of\nhigh-signal intensity within the extramural component on T2 weighting possibly\nrepresenting a mucinous component.\n\nThere are multiple enlarged mesorectal lymph nodes, totalling at least four in\nnumber. These measure up to 6 mm in short axis diameter, series 5 image 7. \nThis is compatible N2 stage.\n\nThere is a mildly enlarged superior hemorrhoidal lymph node measuring 7 mm in\nshort axis diameter (series 5, image 2). There are also pelvic side wall\nlymph nodes, measuring approximately 5 mm in short axis diameter bilaterally. \nThere is however a more prominently enlarged medial chain external iliac lymph\nnode on the right measuring 9 mm in short axis diameter (series 5, image 14).\n\nNo focal bone lesion is seen. There is no evidence of free fluid in the\npelvis. There is degenerative change in lower lumbar spine at the L5-S1\nintervertebral disc space with disc desiccation and osteophyte formation\nanteriorly at the endplates at this level.

Please\nevaluate disease and stage with rectal cancer protocol.\n\nCOMPARISON: No prior imaging for comparison.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted imaging were acquired on a 1.5\nTesla magnet including dynamic 3D imaging obtained prior to, during, and after\nthe uneventful intravenous administration of 26 mL of Magnevist. In addition,\n0.25 mg of Levsin was administered intramuscularly to reduce bowel motion and\n100 cc of barium was given per rectum to distend the bowel lumen. Multiplanar\n2D and 3D reformations have been generated on an independent workstation. \n\nFINDINGS: \n\nThere is a large carpet lesion extending from the ano-rectal junction (series\n13, image 51) and involving the distal and mid rectum over a length of 8-9 cm.\nThe anus is not involved and the internal sphincters appear normal. The more\nsuperior extent of the lesion is a little harder to define as the middle\nrectum is collapsed at this point (Se 5:18). It is nearly circumferential in\nsome parts but encompasses the majority of the left lateral wall of the distal\nrectum from approximately 11 o'clock to 6' o clock in the supine position. It\ndemonstrates increased signal intensity relative to the rectal wall on\nT2-weighted imaging (series 5, image 17), abnormal mucosal hyperenhancement\npost-contrast (series 13, image 26), and evidence of restricted diffusion\n(series 11, image 22 and 24). There is abnormal signal that extends into the\nmuscularis propria butther is not definite extension into perirectl fat. There\nis decreased signal intensity spicules on T2-weighted imaging extending from\nthe rectal wall projecting anteriorly at 12 o'clock at the level of the\nseminal vesicles into theperirectal fat (series 9, image 12). However these\nhave a lower signal intensity than tumor on T2-weighted imaging and do not\nenhance similar to tumor post-contrast (Se13:30). Findings likely represent\nfibrosis / desmoplastic reaction seen along the anterior aspect of the rectum\nrather than tumor invasion. These spicules are 10 mm away from the mesorectal\nfascia anteriorly. \n\nThere are numerous perirectal lymph nodes confined within the mesorectal\nfascia. There are greater than 5 nodes which have suspicious features\nincluding heterogeneous dark signal intensity on T2 weighted imaging and\nlobulated outline. The largest nodes are seen anterior to the sacrum measuring\n8-9 mm and 7-8 mm in short axis diameter respectively (series 9, image 7 and\nimage 4). Two other suspicious nodes are seen in the left anterior rectal\nspace measuring 7 mm, 6 mm and 7-8 mm in short axis diameter (Se 9:11,12). The\nremainder of the nodes within the mesorectal fascia all measure approximately\n6 mm in short axis diameter. While these nodes are concerning given their\nmorphology, in the setting of chronic active colitis and dysplasia only seen\non biopsy it is extremely difficult to be definitive on MRI whether these are\ninvolved by a neoplastic process. If repeat biopsy of the lesion did confirm\nadenocarcinoma then MR staging would be ___ for atleast T2 N2a. \n\nThere is a single 4-mm left external iliac lymph node (series 9, image 8). No\nadditional pelvic adenopathy. No free fluid. Prostate gland and seminal\nvesicles are unremarkable. Visualized bladder is normal. There is a\nfat-containing left inguinal hernia. Some loculated fluid is seen along the\nright spermatic cord. \n\nBone marrow signal is normal and no osseous lesions are identified.\n\nReformatted images were essential in demonstrating the carpet lesion in the\ndistal rectum (Se 1350b). \n\n\nIMPRESSION:\n1. Large carpet polypoid lesion extending from the ano-rectal junction and\ninvolving the entire distal rectum and inferior mid rectum, mostly from 11\no'clock to 6' o clock in the supine position. There is apparent invasion of\nthe muscularis propria but not the perirectal fat. While this is supicious for\nadenocarcinoma on MRI it is extremely difficult to differentiate adenoma and\ncarcinoma in these cases. If repeat biopsies did return adenocarcinoma then by\nMRI it is concerning for T2. \n\n2. Greater than 5 suspicious perirectal lymph nodes. While these nodes are\nconcerning if adenocarcinoma is present, in the setting of chronic active\ncolitis it is difficult to be definitive about their involvement by cancer. If\nrepeat biopsy of the lesion did confirm adenocarcinoma then MR staging would\nbe concerning for at least N2a. It may be possible to target these nodes for\nbiopsy if needed.\n\nFINDINGS WERE REVIEWED WITH ___. ___ IN PERSON ON ___ AT\n8:52AM.\n\n\n", "rows": [ { "field": "Age", "GPT 5.5 Output": "not

Rectal contrast\nsolution consisting of Gastromark and Redicat was administered via a foley\ncatheter. Multiplanar 2D and 3D reformations and subtraction images were\ngenerated on an independent work station. No prior study for comparison.\n\nFINDINGS:\nThere is a polypoid enhancing mass along the right rectal wall with inferior\nborder 1 cm proximal to the anorectal sling. The mass is 1.9 x 1.7 cm and\ninvolves less than 30% of the circumference of the rectal wall. It is\ncompatible with the patient's known rectal cancer. There are two vessels\nadjacent to each other in the right perirectal fat that penetrate the rectal\nwall at the site of the tumor. Minimal nodularity along one vessel on series\n4, image 20 and on series 100, image 67 may be due to ectasia or adjacent tiny\nnode. No vascular invasion or transmural invasion of the tumor. Distance from\nthe tumor to the right lateral mesorectal fascia is 3-4 mm. There are no\nperirectal nodes larger than 4 mm.\n\nThe rectal mass is separate from the bladder. There is colonic diverticulosis.\nNo evidence of bowel obstruction. There are subcentimeter bilateral external\niliac nodes measuring upto 5 mm in short axis on the left.\n\nThere is a T1 hypointense and T2 hyperintense lesion in the left ovary\nmeasuring 5.8 x 3.9 x 4.3 cm. This was also noted on the prior ultrasound of\n___ when it was measured as 5.1 x 4.3 x 3.6 cm, the difference in size may\nbe technical. The uterus and right adnexa appear unremarkable.\n\nMultiplanar 2D and 3D reformations delineated the dynamic series with multiple\nperspectives. A critical finding notification was placed in InfoRadiology.\n\nIMPRESSION:\n1. Polypoid mass just proximal to the anorectal junction along the right\nrectal wall compatible with the patient's known rectal cancer. This appears to\nbe MR stage T2 N0. Large Tis and T1 lesions can be indistinguishable from T2\nlesions on MRI and rigid endorectal ultrasound correlation is recommended.\n\n2.

Staging.\n\nPROTOCOL: MR rectum.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted images were acquired on a 1.5 T\nmagnet including dynamic 3D imaging obtained prior to, during and after the\nuneventful intravenous administration of 18 mL of gadolinium. In addition, 1\nmg IM glucagon was administered. Rectal contrast consisting 150 cc of 8:1\nReadiCAT and GastroMARK was administered via Foley catheter.\n\nMultiplanar 2D and 3D reformats and subtraction images were generated on an\nindependent workstation.\n\nFINDINGS: \n\nThe perianal region is grossly unremarkable. \n\nThere are a number collections in the lower perirectal region surrounding the\nrectum just above the levator plate. These have high signal on T2W images,\nrim enhancement, with nonenhancement centrally. In addition, there appear to\nbe several foci of nondependent susceptibility, suggesting air within these\ncollections. These have the appearances of perirectal abscesses/phlegmon.\n\nThe largest is on the left, has a crescenteric shape wrapping posteriorly and\nto the right measuring 42 x 5 mm on axial images, and extending from the 1:00\nto 8:00 position (series 9, image 22; 201:67). Where this collection crosses\nthe 6:00 location posteriorly, there appears to be communication (8:16) to a\nsmall 7 x 20 mm loculated collection/phlegmon slightly inferior, either within\nor along the puborectalis muscle (9:25; 201:55). Along the right side of the\nlower rectum, just above the levator plate, there is a small 8 x 17 mm focus\nfrom the 7:00 to 10:00 location (9:23; 201:58). \n\nRelation of these supralevator collections to the levator ani is best\nappreciated on T2-weighted coronal images (series 10) and oblique postcontrast\ncoronal images (series 957).\n\nThe adjacent rectum appears compressed by these collections and there is\nsignificant induration of the adjacent perirectal fat, in addition to\nprominent perirectal vessels, predominantly on the right.\n\nA largely endoluminal lesion with heterogenous high signal on T2W images\n(___) and low level heterogeneous enhancement after contrast (200:71-87)\nis seen, perhaps arising from the anterior wall of the rectum (difficult to\ndetermine due to nondistention of the rectum. Maximal ___ are 25 x 38\nmm on oblique axial images (203:16) and 29 mm along the axis of the rectum\n(sagittal 202:15).\n\nAdjacent to this and extending up to 6 cm proximal to this region (the\nsuperior most extent of our imaging), there appears to be slight thickening of\nthe anterior rectal wall both on T2W images (8:17) and on post-contrast images\n(202:17). However, the significance of this finding is difficult to assess\ngiven the significant inflammatory changes noted about the rectum. \n\nThere are left internal iliac lymph nodes, up to 9mm (series 9, images ___. \nLeft lymph node adjacent to the gluteal vessels and piriformus muscle measures\nup to 11 mm short axis (9:14). A similarly located lymph node on the right\nmeasures 5 mm (9:13).

Three perirectal collections are noted around the lower rectum just above\nthe levator ani. The imaging features are suggestive of perirectal sepsis; it\nis unclear whether this may be related to the patient's underling endoluminal\nmass vs the recent interventions, or the preparations for the prior\ninterventions. However, this does not seem to correlate with the clinical\npresentation per discussion with Dr. ___ on initial clinic visit one\nday prior to the examination) at the time of report signing. This findings\nalso discussed with Dr. ___ at the time of report signing.\n\n2. Largely exophytic lesion arising from the anterior wall of the rectum, not\na typical appearance of rectal adenocarcinoma. This may represent the\npreviously noted condyloma.\n\n3. Suggestion of anterior rectal wall thickening for at least 6 cm proximal to\nthe above lesion - it is unclear whether this represents dysplastic/neoplastic\nchange or inflammatory reaction.\n\nRe-imaging after treatment of the perirectal collection and reduction of\nperirectal inflammation may help in delineation of the assessment of the\nendoluminal rectal mass as well as anterior rectal wall thickening.\n\n", "rows": [ { "field": "Age", "GPT 5.5 Output": "not mentioned", "GPT Output, modified by Annotator Radiologist where necessary": "not mentioned" }, { "field":

"INDICATION: Colonoscopy with obstructing rectosigmoid mass, biopsied as\nadenocarcinoma.\n\nNo prior examinations for comparison.\n\nTECHNIQUE: Sagittal T2, coronal T2, axial T2, axial T2 oblique, axial\ndiffusion-weighted, axial 3D SPGR fat saturation pre- and diphasic\npost-contrast images with subtraction were acquired through the pelvis. 9 mL\nof intravenous Gadavist, 100 mL of intrarectal gel, and 1 mg of intramuscular\nglucagon were administered without complications.\n\nFINDINGS: Examination is suboptimal due to patient motion. \n\nApproximately 14 cm from the anal verge, involving only a small part of the\nproximal rectum and more in the sigmoid colon, is a 7-cm-long circumferential\nulcerated mass. This demonstrates irregular wall thickening up to 1-1.5 cm,\nwith intermediate T1 and heterogeneous T2 signal, heterogeneous contrast\nenhancement, and clear restricted diffusion. \n\nTumor invades through the entire wall in a few locations, both anteriorly and\nposteriorly from the lower sigmoid colon with multiple nodules extending to\nthe posterior mesorectal fascia and up to the peritoneum anteriorly. \nAnteriorly the tumor extends up to the peritoneum in several locations and\nthere is focal angulation that suggests tethering of the peritoneal surface of\nthe posterior uterus (8:16, 1101:58), which would indicate extension through\nthe peritoneum. There is no definite myometrial invasion. A few tumor\nextensions from the mass posteriorly to the right show extramural vascular\ninvasion (EMVI). At least seven suspicious mesorectal and sigmoid lymph nodes\nmeasuring 5 mm or more in size. No non-regional nodes suspicious for\ninvolvement.\n\nModerate caliber narrowing is present at the tumor, but without functional\nobstruction. Proximal sigmoid colon demonstrates scattered diverticula,\nwithout acute inflammation. Distally, the rectum is distended to 6 cm, with\ninternal air-fluid level.\n\nIntramural and subserosal fibroids within the uterus. Nabothian cysts are\npresent in the cervix. Superior to the right ovary, a 3 x 1 cm area of\nspiculated enhancing soft tissue along the right pelvic sidewall (6:13) is\nconcerning for drop metastasis. \n\nThere is a small fat-containing periumbilical hernia, which contains the\nantimesenteric portion of a loop of ileum (Richter hernia). The bladder and\ndistal ureters are unremarkable. Mild free fluid in the pelvis and paracolic\ngutters.\n\nThere is multilevel degenerative disease in the lumbosacral spine. No\nsuspicious bone lesions.\n\nIMPRESSION:\n1. 7 cm rectosigmoid cancer with circumferential involvement, ulceration, and\nextensive extramural extension that appears to involve the peritoneum anterior\nto the distal sigmoid and may extend through the peritoneum into the\nperitoneal surface on the posterior uterus, but no definite uterine myometrial\ninvasion. Extramural vascular invasion is present. Seven suspicious perirectal\nand sigmoid lymph nodes. Suspect Stage T4a N2b disease.\n\n2.

rectal cancer, status post neoadjuvant chemotherapy\nand radiation. An EUS at ___ demonstrated a positive lymph node. \nEvaluate prior to surgical planning.\n\nTECHNIQUE: T1- and T2-weighted multiplanar images of the pelvis were acquired\nin a 1.5 T magnet.\nIntravenous contrast: 12 cc Gadavist. Note, the patient only received 0.5 mg\nof glucagon IM due to a prior reaction (nausea/vomitting) when she had\nreceived the full dose.\n\nCOMPARISON: Rectal MRI from ___.\n\nFINDINGS: \n\nSince the prior exam, there has been a significant decrease in size of the\ntumor in the rectum. Approximately 66 mm from the anal verge, in the area of\nthe previously identified tumor, there is minimal residual enhancement (101,\n64), which extends approximately 10 mm in the craniocaudal dimension and\nmeasures 8 x 2 mm in the transverse dimension. There is no associated\nrestricted diffusion, and on the T2-weighted images, the rectal wall looks\nnormal. This abnormal enhancement is confined to the mucosal and submucosal\nlayers, and may represent post treatment changes. By imaging standards, this\nrepresents a complete response to treatment.\n\nAdditionally, there has been a decrease in size of the surrounding lymph\nnodes. The example the previously identified 7 x 5 mm lymph node to the right\nof the rectum now measures 4 x 2 mm (101, 41). Other sub-5-mm mesorectal\nlymph nodes have also decreased, including one which was immediately adjacent\nto the tumor in the prior exam (1001, 50), and is now barely visible. \nAdditionally, there is a 3 x 1 mm lymph node in the right mesorectal fat which\npreviously measured 5 x 3 mm (101, 70). No new lymph nodes are identified.\n\nThere are several pelvic sidewall and inguinal lymph nodes, which are not\nsignificantly changed from the prior exam, and normal in size. There are no\nsuspicious morphologic features.\n\nThe uterus is normal in size. There is a 1.1 cm exophytic fibroid extending\nfrom the fundus (102, 17). This is unchanged from the prior exam. Nabothian\ncysts are noted in the cervix. The ovaries are normal. There is no free\nfluid in the pelvis.\n\nThe bladder wall is trabeculated and irregular, with a somewhat focal polypoid\narea of thickening along the posterior aspect of the bladder (4, 20). This is\nsimilar to the prior exam. The previously identified enhancement in the\nbladder wall has nearly completely resolved.\n\nThere are no concerning osseous lesions. Incidentally noted is chronic dural\nectasia and bony remodeling of the sacrum. The soft tissues are unremarkable.\n\n\nIMPRESSION: \n\n1. Significant interval decrease in size of the rectal tumor with no definite\nremaining tumor and only minimal residual mucosal enhancement. By imaging\nstandards, this represents a complete response, as this enhancement could be\npost treatment changes and there is no abnormality detected on the diffusion\nweighted images or the T2-weighted images.\n2. Interval decrease in size of the mesorectal lymph nodes.\n3. Unchanged subcentimeter pelvic and inguinal lymph nodes, which have no\nsuspicious features.\n4. Unchanged bladder wall trabeculation with an area of polypoid thickening\nalong the posterior aspect of the bladder wall. This suggests chronic outlet\nobstruction, though correlation with symptoms, as well as urine cytology\nand/or cystoscopy is recommended if clinically indicated.\n5.

There is continued thickening of the anterior and posterior aspect of\nthe rectum at this level (series 10, image 49). The inferior edge of the mass\nis approximately 6.0 cm from the anal verge.\n\nThere are two areas of nodular enhancement along the posterior lateral aspect\nof the mass on the right, extending through the mesorectal fat and abutting\nthe circumferential resection margin (series 10, image 49; series 5, image\n15). It is difficult to distinguish whether this reflects residual tumor\nversus scar/fibrosis. However, there remains some areas of restricted\ndiffusion internally on the high b-value series (series 6, image 20; series 7,\nimage 20). The mass is also in contact with the right levator ani muscle and\nthere is associated increased signal intensity within the muscle (series 10,\nimage 52 and series 4, image 27); raising concern for early infiltration.\nThere appears to be a thrombosed vessel at the level of the posterolateral\naspect of the mass on the right, suspicious for extramural tumor venous\ninvasion (series 10, image 48). The constellation of findings are suspicious\nfor T4b disease.\n\nMultiple mesorectal lymph nodes are all below 5 mm except for one (series 10,\nimage 11, 16, 17, 25, 43, 44, 16). There has been interval response of the\nlargest lymph node, now measuring 4 mm, previously 1 cm (series 10, image 17).\nNone of the lymph nodes demonstrate suspicious morphology.

Severe degenerative changes are noted at\nthe left hip joint with an associated small joint effusion. Smooth bone\nmarrow hyperintensity in the lower lumbar spine and sacrum is likely secondary\nto post radiation changes.

diagnosis of rectal cancer. Please evaluate extent of disease.\n\nTECHNIQUE: Multiplanar T1 and T2 weighted imaging was obtained on a 1.5 T\nmagnet, including dynamic 3D imaging obtained prior to, during and subsequent\nto the intravenous administration of 0.1 mmol/kg of Gadavist (7 ml). 1 mg of\nintramuscular glucagon was administered to reduce bowel motion.\n\nFINDINGS:\n\nThere is an irregular mass in the distal rectum extending over a distance of\napproximately 5 cm in craniocaudal dimension. It arises 5 cm from the anal\nverge (3,16) and is approximately 6 mm superior to the puborectalis muscle (4,\n22). The wall of the rectum is circumferentially involved from the 10 o'clock\nto 5 o'clock positions (6, 16). There is some irregularity of the muscularis\npropria with minimal stranding extending into the perirectal fat (6, images\n11, 13 and 17). This most likely represents a desmoplastic reaction associated\nwith the tumor however direct T3 tumor extension cannot be excluded. There is\nalso the suggestion of extramural vascular invasion (EMVI) with loss of the\nflow voids (6, 15) and hypoenhancement (400, 59) of small mesorectal veins\ncompared to adjacent veins on post contrast imaging.\n\nThere are 3 enlarged nodes within the mesorectal fat which demonstrate\nheterogenous enhancement post administration of contrast and are suspicious in\nnature. There are two 6 mm nodes at the level of the tumor (5, 24 and 5, 23)\nwith a further 6 mm noted superiorly (5, 32). There is a further 5 mm node\nslightly more superiorly again (5, 35) which is also suspicious in nature,\nlikely involved. Several small sub 5 mm nodes are noted within the right side\nof the mesorectal fat (series 5, 24 and 23). There is 3 mm of distance\nbetween the most lateral involved node and the mesorectal fascia (5, 23). \n\nNo invasion into the prostate and seminal vesicles. The bladder is\nunremarkable. No bowel obstruction.\n\nNormal signal within the visualized skeletal system.\n\nIMPRESSION:\n\nIrregular enhancing tumor within the right lower rectum approximately 5 cm\nfrom the anal margin extending for a distance of 5 cm. There is some\nirregularity at the junction of the muscularis propria however on balance it\nis felt to represent a T2 lesion. There is probable extra mural venous\ninvasion. \n\nThere are 3 mesorectal nodes measuring 6 mm in short axis dimension with a 5mm\nnode more superiorly, consistent with N2 disease.

RECTAL\n\nINDICATION: Newly diagnosed rectal cancer.\n\nCOMPARISON: No prior imaging for comparison.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted imaging were acquired on a 1.5\nTesla magnet including dynamic 3D imaging obtained prior to, during and after\nthe uneventful intravenous administration of 7 mL of Gadavist. In addition,\n60 mL of 0.9% barium sulfate was administered per rectum and 1 mg of\nintramuscular glucagon was administered to reduce bowel motion.\n\nFINDINGS: \n\nThere is a large near circumferential carpet-like lesion involving the lower\nrectum extending over a craniocaudal extent of approximately 7 cm. The\ninferior margin is approximately 4.5 cm from the anal verge and commences just\nabove the level of the puborectalis muscle with apparent sparing of the\ninternal sphincter. There is extension of the tumor through the wall of the\nrectum in a perivascular distribution approximately at 10 o'clock in the\nsupine position (series 7, image 18, series 8, image 22 and series 1001, image\n54), concerning for a T3 lesion. \n\nThere are two large internal iliac/obturator lymph nodes identified on the\nright side, the largest of which measures 11 x 10 mm (series 7, image 9) with\na more medially placed lymph node measuring 10 x 10 mm. This more medial node\nappears a little bit darker on T2-weighted imaging and is hypoenhancing\nrelative to the adjacent lymph node and also contains some bright signal on\nthe precontrast T1-weighted imaging, which may suggest a degree of\ncalcification within this lymph node (series 9, image 37). There are also\nnumerous lymph nodes identified within the mesorectal fascia. The larger of\nthese measures 7 mm and 5-mm respectively in the mesorectal fascia adjacent to\nthe left lateral wall of the rectum (series 7, image 15), in the presacral\nspace measuring 5 mm (series 7, image 16) and adjacent to the right lateral\nwall of the rectum within the mesorectal fascia measuring 4 mm (series 7,\nimage 10). There are also many sub-5-mm lymph nodes noted in the mesorectal\nspace, which also have a rounded morphology and are hypervascular and these\nare also concerning for other foci of metastatic lymph node metastases though\nnot by size criteria. Findings are concerning for N2a disease. \n\nAdjacent to the more inferior aspects of the tumor (series 1002, image 80),\njust above the junction of the puborectalis and levator ani, the\ncircumferential resection margin is very small (less than 3 mm) given the\npaucity of perirectal fat separating the low rectum and the adjacent\npuborectalis/levator ani muscles. \n\nThere has been prior hysterectomy. The ovaries are not visualized. \nVisualized portions of the bladder and sigmoid colon are unremarkable. There\nis no free fluid in the pelvis.\n\nBone marrow signal is normal. There are no osseous lesions. \n\nIMPRESSION:\n\n1. Near circumferential carpeting lesion involving the distal rectum\nextending over a craniocaudal extent of approximately 7.2 cm. There is\nperivascular tumor extension through the wall of the rectum at approximately\n10 o'clock in the supine position (series 1002, image 56). Findings are\nconcerning for a T3 lesion.\n\n2.

local disease\n\nTECHNIQUE: T1- and T2-weighted multiplanar images of the pelvis were acquired\nin a 1.5 T magnet.\nIntravenous contrast: 10 mL Gadavist\n\nCOMPARISON: Comparison made to CT from ___.\n\nFINDINGS: \n\nRECTUM AND INTRAPELVIC BOWEL:\nThere is a tubulovillous mass centered in the lower rectum in the right\nlateral rectal wall extending from roughly 6 o'clock to 12 o'clock along its\nattachment, though the mass itself extends from 5 o'clock to 1 o'clock. The\nmass appears ulcerated. It measures up to 5.3 cm in greatest dimension. The\nmost distal apparent attachment site of the mass is likely located 1.5 cm\nabove the anorectal junction, but the tumor soft tissue is less than 1 cm from\nthe anorectal junction. The muscularis propria is not well seen in a few\nareas on the T2 weighted imaging (08:14, 08:16, 08:18) and there is\nirregularity along the perirectal fat the without clear extension of tumor\nbeyond the wall. No definite extension of tumor beyond the muscular propria\nand into the perirectal fat, though there are areas where it appears to extend\ninto the muscularis propria and potentially with full-thickness extension\nthrough the muscular. The circumferential resection margin is not involved.\n\nMultiple nodes are appreciated immediately adjacent the lesion in the\nperirectal fat, with a few measuring more than 5 mm, with the largest 6 mm\n(8:2), but normal morphology and normal in signal intensity on all sequences\nis appreciated. Additional lymph nodes are seen in the right high perirectal\nfat(04:15) measuring 6 mm, and more superiorly in the left pelvis largest\nmeasuring 6 mm (4:7) and 9 mm (4:4), also exhibiting normal morphology and\nsignal intensity. Lateral pelvic sidewall lymph nodes are seen relatively\nsymmetrically within the external iliac chain but there are no concerning or\nasymmetric internal iliac lymph nodes.\n\nScattered colonic diverticulosis within the sigmoid.\n\n\nUTERUS AND ADNEXA:\nAnteverted uterus measures 4.0 x 5.5 x 7.4 cm. There is abnormal thickening\nof the endometrium measuring up to 2.2 cm. There is also abnormal restriction\nof the endometrial contents. The abnormal soft tissue is predominantly\nconfined within the endometrium and does not extend into the cervix. However,\nthere is slight irregularity within the myometrium in the cornual bilaterally,\nthat may represent early myometrial invasion that is well less than 50%. No\nextrauterine extension of tumor. Bilateral adnexa are normal in appearance\nwith normal postmenopausal ovaries. Nabothian cyst is seen distally within\nthe cervix.

adenocarcinoma status post definitive resection after\nneoadjuvant chemoradiation on ___ when a low anterior resection with\nend-colostomy was performed. Review of the operative note is pertinent for a\nmention that the majority of the rectum was removed at this time. The patient\nalso had a subsequent exploratory laparotomy with ileocecectomy and lysis of\nadhesions in ___ for small-bowel obstruction. The patient is currently\npresenting with increased ostomy output and rectal pressure with pinkish mucus\nthrough the anus.\n\nComparison is made to prior CT examination dated ___, and ___.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted images were obtained through the\npelvis on a 3T magnent prior to and after the uneventful administration of 15\nmL of intravenous Magnevist contrast. A small amount of GastroMARK with\nbarium was introduced through the anus with a Foley catheter.\n\nMultiplanar 2D and 3D reformations were created on a separate workstation and\nwere crucial for full delineation of vascular and bowel pathology.\n\nMRI OF THE PELVIS WITHOUT AND WITH INTRAVENOUS CONTRAST.\n\nAgain noted is an elongated bilobed fluid collection within the posterior\npelvis which extends along the anterior aspect of the coccyx to the mid-to-\nlower sacrum which has a craniocaudal extent of approximately 12 cm and is not\nappreciably changed in size compared to the prior CT examinations dating back\nto ___. The instilled rectal contrast displays low T1/T2 signal with the\nfluid within the collection which communicates with the anus, displaying iso-\nto slightly low T1 signal in comparison to the surrounding musculature and\nhigh T2 signal. Of note, the instilled contrast does not appear to mix freely\nwith the fluid within the collection, suggesting a gelatinous/mucinous\nconsistency. Post-contrast administration, this collection displays thickened\nirregular enhancement with a small nodular enhancing component noted along the\nright posterolateral aspect measuring approximately 5 mm (series 200, image\n82). The collection is again noted to be bilobed with a 6-mm waist separating\nthe dominant superior and inferior components noted on the axial images. Some\ninflammation and enhancement is noted surrounding the fluid collection which\nmay relate to acute inflammation or prior radiation-type changes. No\nsuspicious solid nodular enhancing components to suggest local recurrence are\nidentified. No pathologically enlarged presacral, pelvic sidewall, inguinal,\nor ___ distribution nodes are identified with a few small sub 5-mm presacral\nnodes present. No fistulous connection to adjacent vagina is noted in this\npatient status post TAH-BSO. Residual presacral soft tissue which is likely\npost-surgical/post-treatment- related is again noted which is not\nsignificantly changed in appearance from prior CT examinations.\n\nPost-surgical changes from prior ileocecectomy are noted. Region of band-like\nscarring is again present projecting off the posterior aspect of the remaining\ncecum towards the fluid collection without any rectal contrast or fluid within\nit and mild enhancement noted post-contrast (series 200, image 73). The\nascending colon is predominantly collapsed but displays a slightly thickened\nwall without any significant hyperemia noted post-contrast administration. The\nremaining large bowel including the visualized ostomy appears unremarkable\nwith mild diverticulosis again identified. Artifact from surgical clips and\nsome calcification surrounding the presacral fluid collection is not\nappreciably changed from ___ CT exam. No additional soft tissue or bony\npathology is present. The decompressed bladder appears unremarkable.\n\nIMPRESSION:\n1. No significant change in size to presacral fluid collection which is now\nshown to freely communicats with the anus. It contains gelatinous fluid\ncontents. The thickened irregular and partially nodular wall enhancement of\nthe collection appears progressed from ___ CT exam, suggesting acute\ninflammation or superinfection.\n\nOf note, the collection is bilobed with a 6- mm waist at its center which may\nprevent evaluation of the superior component via physical exam or anoscopy;\nhowever, the more inferior component continuous with the anus may be amenable\nto visual inspection/biopsy if needed clinically.\n\n2. No findings to suggest rectal carcinoma recurrence with stable\npostoperative soft tissue within the presacral space and no pathologically\nenlarged lymph nodes.\n\n3. Underdistended but slightly thick-walled ascending colon of uncertain\nsignificance. This may reflect post-radiation changes.\n\nAn e-mail was sent on the date of exam to the primary care physician, ___.\n___ oncologist, Dr. ___ the above findings.\n", "rows": [ { "field": "Age", "GPT

Evaluate site and please\nstage cancer.\n\nTECHNIQUE: T1- and T2-weighted multiplanar images of the pelvis were acquired\nin a 1.5 T magnet.\nIntravenous contrast: 6 mL Gadavist.\n\nCOMPARISON: CT of the abdomen and pelvis from ___.\n\nFINDINGS: \n\nThere is a mass at rectosigmoid junction, with the most distal portion of the\nmass approximately 14 cm from the anal verge. The mass is 33 mm in length. \nThe bulk of the mass actually appears to be in the sigmoid, with only a small\npart of the mass extending into the upper rectum. It is circumferential in\nshape.\n\nAt 1 o'clock, the mass extends through the muscularis propria, where there is\nabout 4 mm of extramural spread (5, 14). Linear low signal on the T2 weighted\nimages in this area reflects extramural venous invasion. This linear low\nsignal enters into a irregular mass of low signal that measures 11 x 9 mm (12,\n47), which likely represents the tumor deposit with an underlying involved\nlymph node. Additionally, are two other suspicious lymph nodes, one which\nmeasures 5 mm lymph node (5, 15) and one which measures 3 mm (5, 12). Despite\nthe small size of this 3 mm lymph node, there is surrounding haziness in the\nadjacent fat (12, 47), which likely is due to extramural venous invasion in\nthis area.\n\nAt the proximal edge of the tumor, along the inferior aspect of the mass, at\napproximately 6 o'clock, the wall becomes indistinct and there appears to be\ninvasion through the muscularis propria (12, 49 and 5, 13). There is about 4\nmm of extramural spread (5, 13). This spread involves and crosses below with\nthe peritoneal reflection. Immediately adjacent to this spread, there is a 5\nmm T2 hypointense lymph node which sits directly on the mesorectal fascia (6,\n15).\n\nThere is a focus of desmoplastic reaction at the 3 o'clock region (5, 14)\nwhich is causing some tethering and curvature of the mass.\n\nNo other areas of muscularis propria involvement or extramural spread are\nidentified in the tumor. Specifically, the area of the tumor and in the upper\nrectum appears to be confined within the muscle.\n\nTogether, these findings would make the tumor a T4a due to the involvement of\nthe peritoneal reflection. It would also be a N2a because there are four\nsuspicious lymph nodes; three above the tumor, with two being discrete lymph\nnodes and one being involved in the tumor deposit; as well as one below the\ntumor at the mesorectal fascia.\n\nPlease see the tumor table below for further details.\n\nTUMOR TABLE:\n\nTumor: Circumferential, at the rectosigmoid junction, predominately within\nthe sigmoid\nDistance from anal verge (AV) (mm): 138 mm\nExtends cranio-caudally (CC) (mm): 33 mm\n\nSTAGING\nInvading tumor edge: At 1 o'clock and at 6 o'clock\nMuscularis propria: Involved\nExtramural spread (mm): 4 mm (in two locations)\nExtramural venous invasion (EMVI): Present\nPeritoneal reflection: Involved\nAdjacent pelvic organs ___, prostate): Not involved\n\nCRM (Circumferential resection margin): There is an encapsulated lymph node\nat the superior most aspect of the mesorectal fascia at 2:30 o'clock\n\nMesorectal lymph nodes - Size (mm): 5 mm\nMesorectal lymph nodes - location: Superior aspect of the mesorectal fascia\nMesorectal lymph nodes - heterogeneous signal: No\nMesorectal lymph nodes - capsular irregularity: No\nMesorectal lymph nodes: 1\n\nPelvic side wall nodes: none\n\nLocal mesenteric lymph nodes superior to the tumor - Size (mm): 5 mm, 3 mm,\nand unknown because it is involved within a tumor deposit\nLocal mesenteric lymph nodes superior to the tumor - heterogeneous signal: No\nLocal mesenteric lymph nodes superior to the tumor - capsular irregularity: No\nLocal mesenteric lymph nodes superior to the tumor: 3\n\nStaging Assessment: T4a, N2a, M1b (because of peritoneal involvement at the\nperitoneal reflection and well as suspected osseous involvement)\nExtramural spread (mm): 4 mm\nCRM: involved\nEMVI: present\nLocation: Rectosigmoid junction, though mostly sigmoid\n\nThere is a small amount of free fluid in the pelvis, which is nonspecific. No\ndistant lymph nodes are identified, other than those described above in the\ntumor table. The mid and lower aspect of the rectum demonstrates mild mucosal\nedema, which is nonspecific. No other tumor is identified. There are no\nsurrounding inflammatory changes around the mid and lower rectum, or in the\nremainder of the intrapelvic bowel loops.\n\nThe bladder is collapsed, which limits its evaluation. There is likely some\ntrabeculation and small diverticula (6, 11). A cystic appearing structure\nalong the anterior superior aspect of the bladder (3, 28), may represent\nanother small diverticulum, or tiny urethral cyst. There is a\nbenign-appearing 11 mm cyst in the seminal vesicles. The seminal vesicles and\nimaged portions of the prostate gland are otherwise normal.\n\nIn the right aspect of the L5 vertebral body, there is a 10 mm lesion which is\nlow signal on the T2 weighted images and enhancing (5, 20 and 12, 60). There\nis no correlate on the CT. This is suspicious for a metastasis. No other\nosseous lesions are identified. The soft tissues are unremarkable.\n\nIMPRESSION: \n\n1. Mass at the rectosigmoid junction, with the bulk of the lesion along the\nsigmoid aspect, as detailed above. There is extramural spread, extramural\nvenous invasion, involvement of the peritoneal reflection, and four suspicious\nlymph nodes, including one along the superior aspect of the CRM. Radiologic\nstage T4a, N2a.\n2. 10 mm enhancing osseous lesion in L5 is suspicious for metastasis. \nFurther evaluation with a bone scan or PET scan is recommended. This would\nrepresent M1b disease, both due to this lesion and involvement of the\nperitoneal reflection near the primary mass.\n\nRECOMMENDATION(S): Bone scan or PET scan.\n", "rows": [ { "field":

___.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted MR images of the pelvis were\nperformed prior to, during and after uneventful intravenous administration of\n7 mL of Gadavist in a 1.5 Tesla magnet.\n\nFINDINGS: Approximately 4 cm above the anal verge, spanning a craniocaudal\ndistance of about 6.2 cm is a hemi-circumferential polypoid mass involving the\nleft lateral wall of the lower rectum (4:16). The inferior margin of this\nlesion abuts the internal sphincter and puborectalis muscles (12:54). The\nmass invades the muscularis propria, with no definite extension beyond into\nthe perirectal fat, suggesting T2 stage tumor (6:6, 8:13). This tumor is\nhyperintense on T2-weighted images, hypointense on T1-weighted images, and\nshows progressive low-level enhancement in the dynamic post-contrast images. \nMultiple perirectal lymph nodes (>4) include a 7mm right perirectal lymph node\n(13:42), 10 mm right perirectal (13:47), a 8 mm left perirectal (13:47), a 5\nmm node (13:71), 5 mm node (13:71). Few additional lymph nodes measuring less\nthan a centimeter are seen along the inferior mesenteric chain (5:2). The\nfindings are worrisome for N2 stage disease. Circumferential resection margin\nis negative, with the closest CRM from an abnormal perirectal lymph node\nmeasures 4 mm. \n\nThe uterus is anteverted and anteflexed, measuring 7.6 x 3.5 x 6.0 cm. The\nendometrial cavity is thickened, measuring 9 mm. The endometrial-myometrial\ninterface is irregular with few cystic areas extending into the myometrium. \nAlso seen are small T2 hypointense within the ednometrial cavity, which appear\nto be enhancing (4:16, 13:49). The ovaries are unremarkable. \n\nScattered sigmoid colonic diverticulosis is seen. The urinary bladder is\nnormal. Small bilateral external iliac lymph nodes are not pathologically\nenlarged. There is no pelvic free fluid. No marrow signal abnormality is\nseen.\n\nIMPRESSION:\n\n1.

There is significant desmoplastic reaction\nsurrounding the tumor posteriorly. There are multiple (more than 4)\nheterogenous lymph nodes within the perirectal space with heterogenous signal\nand irregular margins consistent with metastatic disease. The closest\ndistance of an involved perirectal node to the mesorectal fascia, ie the\ncircumferential resection margin, is about 3 mm (series 6, image 6 and 16). \nThere is also an abnormal node in the left internal obturator chain with\nirregular borders and heterogenous signal measuring 8 x 12 mm consistent with\nmetastatic disease. The mesorectal fascia or pelvic side walls also not\ndirectly involved.\n\nDiffusion weighted images demonstrate restricted diffusion in the tumor and\ninvolved nodes.\n\nThere are two other lesions in the rectum. First is a 7 x 5 mm polypoid lesion\nat posterior wall of the rectum approximately 7.8 cm from anal verge. The\nother lesion is a 1.3 cm mid sigmoid lesion that is predominantly exophytic\nbut is not adequately assessed on post-contrast images, but is seen to\nenhance.\n\nBladder, prostate, seminal vesicles, and visualized pelvic small bowel are\nunremarkable.

surveillance.\n\nTECHNIQUE: Multiplanar T1- and T2-weighted images were acquired on a 1.5\nTesla magnet, including dynamic 3D sequences prior to, during, and after the\nuneventful intravenous administration of 0.1 mmol/kg (15 mL) of Magnevist. 1\nmg of intramuscular glucagon was administered to reduce bowel peristalsis.\n\nMultiplanar 2D and 3D reformations and subtraction images were generated on an\nindependent workstation.\n\nNo previous MR for comparison. Compared to CT scan ___.\n\nFINDINGS:\n\nApproximately 11.5 cm from anal verge, there is an intraluminal mass measuring\n23 mm in craniocaudal, 20 mm in anteroposterior and 15 mm in transverse\ndiameters in the right side of mid to upper rectum, occupying from\napproximately 8 to 11 o'clock circumference. The mass demonstrates\nheterogenous enhancement post-contrast administration and restricted\ndiffusion. There is slight irregularity of the serosal surface on the lateral\naspect of the mass with some tethering and T2-hypointense linear bands,\ndemonstrating gradual low-grade enhancement post-contrast administration,\nwhich may represent stage T3 tumor versus desmoplastic reaction. Overall, the\nmass appears smaller than the CT scan ___, considering the\nlimitations of intermodality comparison.\n\nThere is a 1-cm abnormal enhancing lymph node with irregular borders and a\nnecrotic center in the midline in the presacral region that demonstrates\nrestricted diffusion similar to the primary tumor, suspicious for metastatic\ndisease. This node can not be identified on the prior CT scan. There are\nmultiple morphologically normal and enhancing nodes, 3-4 mm in diameter, in\nthe perirectal and pre-sacral region. \n\nThe previously drained large left pelvic collection now measures 1.3 x 0.6 cm,\nconsistent with near-complete resolution. It demonstrated some enhancement but\nno restricted diffusion.\n\nThere is no free fluid in the pelvis. There is no nodularity of the\nperitoneum.\n\nUterus and ovaries cannot be identified. The bladder is unremarkable. No\nlesion in the visualized pelvic bones.\n\nThere is thickening of the anterior wall of the rectum up to 7 mm that\ndemonstrates mucosal enhancement, most probably of inflammatory nature (such\nas postradiation effect) and unlikely to be neoplastic.\n\nMultiplanar 2D and 3D reformations and subtraction images provided multiple\nperspectives for the dynamic series (407).\n\nIMPRESSION:\n1. First surveillance MRI demonstrating residual tumor in the right\nmid-to-upper rectum with minimal irregularity and tethering in the serosal\nsurface consistent with minimal residual stage T3 tumor versus desmoplastic\nreaction.

an intraluminal mass is seen in the proximal rectum, approximately\n11.5 cm from the anal verge (2:15). The bowel is very tortuous in this region\nmaking accurate measurements difficult; however, in craniocaudal dimension,\nthis lesion measures approximately 2.6 cm (vs. 2.3 cm previously) in\ncraniocaudal dimension. The anteroposterior and circumferential margins of\nthe tumor cannot be assessed on this study. There is continued irregularity\nof the serosal surface at the infero-lateral aspect of the mass, with\ntethering to the peritoneal reflection seen inferiorly (8:23).

Again these are unchanged compared to the prior study\nand may represent postoperative/procedural changes rather than tumor.\n\nThere is an enlarged presacral lymph node with a spiculated margin (5:6)\nmeasuring 1.2 cm on today's study, slightly increased compared to the prior\nstudy when it measured 1 cm (5:6). This node was seen to be FDG-avid on the\nprior PET/CT. \n\nNo free fluid in the pelvis. No pelvic side wall lymph nodes. Sigmoid\ndiverticulosis without diverticulitis.

It extends below the level of the\npuborectalis into the upper anus. Posteriorly at the level of the anorectal\njunction and immediately below it, there is evidence of tumor extension into\nthe perirectal fat posteriorly and on the left side (5:19 and 1002:78) with\n1-2 mm of apparent extension beyond the muscularis propria.

This lesion is 12 cm\nfrom the anal margin. The lesion is slightly hyperintense to muscle on T2-\nweighted imaging. The lesion is submucosal in location with preserved high\nsignal mucosa and submucosa overlying the lesion (series 5, image 13). The\nlesion measures 2.6 x 1.5 x 1.9 cm in diameter. It enhances following\ncontrast administration. It is compatible with the patient's known rectal\ncarcinoid tumor. Of note, the lesion is within 1 mm of the posterior margin\nof the mesorectal fascia.\n\nThere are two visualized mildly enlarged perirectal lymph nodes in the region\nof the tumor. These measure 5 mm (series 3, image 5) and 6 mm (series 3,\nimage 13) in diameter.\n\nThe endometrial cavity is widened. Within the endometrial cavity, there is an\narea of abnormal low signal intensity on T2-weighted imaging projecting into\nthe lumen from the posterior wall. This is compatible with a polypoid lesion.\nThis enhances following contrast administration. This lesion measures\napproximately 0.8 x 1.6 cm in diameter.\n\nThere is a 1.5-cm endometrial fibroid. This is located at the anterior wall\nof the body of the uterus.\n\nNo ovarian mass is demonstrated. There is no free fluid in the pelvis.\n\nMultiplanar 2D and 3D reformations and subtraction images provided multiple\nperspectives for the dynamic series.\n\nIMPRESSION:\n1.

for evaluation of rectal cancer and severe rectal\npain\n\nTECHNIQUE: T1- and T2-weighted multiplanar images of the pelvis were acquired\nin a 1.5 T magnet.\nIntravenous contrast: 9 mL Gadavist.\n\nCOMPARISON: MR pelvis dated ___ and CT abdomen dated ___.\n\nFINDINGS: \n\nRECTUM AND INTRAPELVIC BOWEL: The heterogeneously enhancing anorectal mass,\nwhich is mildly hyperintense on the T2 weighted images and demonstrates\nrestricted diffusion, representing known neuroendocrine carcinoma, is re-\ndemonstrated. The mass measures approximately 5 cm in the CC direction which\nis unchanged compared to the prior exam. However, compared to the prior MR\nthere is interval enlargement of areas of extramural extension. The component\nof the mass on the left posterolaterally at the anal verge, centered at 5\no'clock measuring 18 x 20 mm which extends posteriorly through the muscularis\npropria to the left, is increased in size, having previously measured 1.3 x\n1.2 cm compared to the prior MRI though similar to the recent CT. The\nintersphincteric plane is invaded which is unchanged compared to the prior\nexams.\nAt least 4 additional areas of extension through the muscularis propria/EMVI\nare seen, including left lateral, ___ o'clock (9 a: 46), left anterolateral,\n___ o'clock (9 a: 52), left posterior lateral, 4 o'clock (9a: 57), left\nlateral, 3 o'clock (98:64), and left superolateral, 1 o'clock (9a:65). The\nmajority of these areas are either progressed or new since the prior MRI and\ndifficult to compare accurately with CT, grossly stable to possibly slightly\nprogressed.\n\n\nThe peritoneal reflection and adjacent pelvic organs are not involved. \nHowever, due to progression of extramural vascular invasion of tumor, there is\nlinear extension of metastatic disease along the presacral fascia and within\nthe mesorectal fat, extending superiorly for a distance of approximately 6.5\ncm (03:19), with tumor showing spiculated margins and tethering of the\npresacral fascia (4:8 as representative image). There is also mild presacral\nedema. There is no evidence of an perirectal abscess.\n\nLYMPH NODES:\n\nThere are multiple suspicious, heterogeneously enhancing pelvic lymph nodes. \nFor instance, there is an adjacent right mesorectal lymph node which measures\n6 mm (previously 3 mm, 9a:80). An irregular hypoenhancing left obturator\nlymph node measuring 11 mm (9:84) is unchanged compared to the recent CT scan\nbut slightly larger compared to the prior MRI. This lymph node comes in close\nproximity to the sciatic nerve and shows spiculated margins. A superior\nrectal lymph node measures 8 x 17 mm which is larger compared to the prior MRI\nbut similar to the recent CT (9 x 14 mm on the previous MRI, 3:19).\n\nBLADDER AND DISTAL URETERS: There is a small bladder diverticulum on the\nright.\n\nProstate: In the peripheral zone, there are scattered linear areas of\nhypointense signal on the T2 weighted images with mild heterogeneous\nenhancement. This finding can be seen in the setting of prostatitis.\n\nVASCULATURE: The pelvic vessels are of normal caliber throughout with any\nsignificant areas of narrowing or dilation.\n\nOSSEOUS STRUCTURES AND SOFT TISSUES: There is new trace non-specific free\nfluid in the pre-sacral space. This finding could reflect lymphatic\nobstruction. No rim-enhancing collections. The bone marrow demonstrates\nnormal signal characteristics. No concerning osseous lesions.\n\nIMPRESSION: \n\n1. Heterogeneously enhancing anorectal mass representing known neuroendocrine\ncarcinoma shows increased size and increased perirectal tumor involvement\ncompared to the prior MRI, though without significant change compared to the\nrecent CT.\n2. Multiple metastatic pelvic lymph nodes are grossly stable compared to the\nrecent CT scan. A left obturator lymph node or tumor deposit/EMVI is in close\nproximity to the sciatic nerve with some spiculation and tethering of adjacent\nstructures.\n3. No perirectal abscess or other acute abnormality identified to suggest the\ncause of rectal pain.\n", "rows": [ { "field": "Age", "GPT 5.5 Output": "not mentioned", "GPT Output, modified by Annotator

images\nobtained prior to, during, and after the uneventful intravenous administration\nof 0.1 mmol/kg of gadolinium-DTPA. Multiplanar 2D and 3D reformations and\nsubtraction images were generated on an independent workstation.\n\nFINDINGS: There is confirmation of a rectal mass extending from the 12\no'clock to the 4 o'clock position with the patient in standard lithotomy. The\nmass is predominantly isointense to the rectal wall on T1-weighted images and\npredominantly isointense on T2-weighted images, with a small component of\nperipheral hyperintensity. It is heterogeneously enhancing, with restricted\ndiffusion. It measures 3.6 x 1.7 cm in greatest axial ___ and 4.4 cm\nin greatest craniocaudal dimension and its caudal margin is nearly 8 cm from\nthe anual orifice and 4 cm from the anorectal ring. The mass extends beyond\nthe muscularis propria into the perirectal fat (series 100, image 78). The\nmass is separated from the anterior mesorectal fascia by a 2-mm margin (9,\n60).\n\nThere are three lymph nodes in left mesorectal fat which have somewhat\nirregular margins and are heterogeneously enhancing. These demonstrate\nrestricted diffusion and measure up to 5 mm in short axis (5, 5 and 5, 9).\nAdditional nodes which lie in the fat superior to the mass are non-\npathologically enlarged and homogeneously enhancing (5, 1 and 5, 2). There are\nno pathologically enlarged lymph nodes along the iliac chains or pelvic\nsidewalls. There is no free fluid or focal bone marrow signal abnormality.\nIncidental note is made of a 14-mm thin-walled cystic lesion abutting the\nrectal wall, which is hypointense on T1- weighted images, hyperintense on T2-\nweighted images and non-enhancing. It too lies superior to the mass (5, 4) and\nis an uncertain finding.\n\nMulti-planar 2D and 3D reformations provided multiple perspectives for the\ndynamic series. \n\nIMPRESSION:\nT3N1 stage rectal cancer by MRI mostly in the middle third of the rectum, with\nabnormal nodes within the mesorectal fascia, with a 2- mm margin between the\nmass and the anterior mesorectal fascia.\n", "rows": [ {

"EXAMINATION: MR PELVIS WANDW/O CONTRAST\n\nINDICATION: ___ year old man with new rectal mass // Initial staging- RECTAL\nCANCER PROTOCOL\n\nTECHNIQUE: Multiplanar T1 and T2 weighted MR images of the pelvis were\nobtained on a 1.5 Tesla magnet including dynamic 3D imaging prior to, during,\nand after the administration of 7 mL Gadavist gadolinium based contrast. 1 mg\nof glucagon was administered intravenously to reduce bowel motion.\n\nCOMPARISON: None.\n\nFINDINGS: \n\nApproximately 5 cm from the anal verge at the right-anterior wall of the\ndistal rectum a mass is demonstrated, measuring 1.6 cm in diameter. The mass\nis hyperintense on T2WI relative to the muscularis propria(8:15) and\ndemonstrates restricted diffusion (06:59) and hypoenhancement relative to the\nrectal mucosa (1102:53). The T2 hypointensity of the muscularis propria is\nintact (8:15, 600:16). Minimal linear strands of T2 hypointensity along the\nright anterior rectal wall are compatible with desmoplastic reaction (8:15).\nThis is consistent with T2 lesion.\nNo enlarged mesorectal lymph nodes are demonstrated.\n\nThe prostate gland is enlarged and demonstrates the swirled nodular appearance\nof within prostatic hyperplasia.\nThe seminal vesicles demonstrate T2 hypointensity and intrinsic T1\nhyperintensity, consistent with proteinaceous contents.\nThe urinary bladder wall is trabeculated, secondary to chronic outlet\nobstruction.\nBilateral fat containing inguinal hernias are demonstrated.\nThe bone marrow signal is normal.\n\nIMPRESSION:\n\n\n1. Distal rectal mass located 5 cm from the anal verge at the right-anterior\nrectal wall, with preserved muscularis propria. No enlarged lymph nodes.\nRadiologic stage T2 N0.\n2.
