Colon is predominantly in the left side of the abdomen with cecum in the left lower quadrant.There is reversed SMA/SMV relationship, with the SMV seen to the left of the SMA.No signs of abdominal obstruction.The appendix is in the lower abdomen to the left to the midline. It contains an appendicolith, distended with mural hyperenhancement and periappendiceal inflammatory fat stranding, consistent with acute appendicitis. No signs of perforation. No associated fluid collections.

Response: The pancreas appears bulky and shows an ill-defined isodense hypoenhancing mass measuring approximately 4.3 x 2.0 cm. There is extensive polypoidal thickening of upper gastrointestinal tract wall, involving the pylorus of stomach, duodenum, jejunum and proximal ileum. The polyps measure 5 to 30 mm and causing luminal compromise. The proximal small bowel appears distended till distal ileum and there is an ileo-ileal intussusception noted in the distal ileum. The terminal ileum and large bowel appear collapsed.There are few enlarged non-necrotic lymph nodes noted in the mesentery, the largest lymph node measures 1.3 x 0.8 cm in size. There is a well defined oval mass measuring approximately 6.0 x 4.5 cm noted in the right adnexa. The right ovary could not be separately visualized from the mass. The mass shows post contrast enhancement and central non-enhancing necrotic region within.Extensive polypoidal mucosal thickening predominantly affecting the upper gastrointestinal tract with pancreatic and ovarian neoplasms are likely to represent gastrointestinal polyposis syndrome most likely Peutz Jeghers Syndrome.

Response: Abdominal CT scan shows a lobulated mass within the lower part of the right rectus abdominis muscle. The mass is hyperattenuating compared with muscle.The differential diagnosis remained unchanged from the previous ultrasound examination. Endometriosis was considered the most probable diagnosis, based on the typical location in the area of the Caesarian scar. Fibromatosis and other soft tissue tumors were included in the differential diagnosis as well.Additional findings: Multiple hypodense wedge areas in the right kidney cortex, compatible with pyelonephritis.

Response: Imaging of the abdomen and pelvis was performed after contrast bolus injection. This revealed absence of contrast opacification of left heart and aorta. Retrograde opacification, layering, and pooling of contrast was noted within the dependent aspects of the inferior vena cava, hepatic veins, and right renal vein. Contrast opacified the dependent aspect of the right hepatic lobe parenchyma.

Response: There is evidence of right aortic arch coursing between trachea and oesophagus. The first and second branches arising from right arch are right common carotid and right subclavian artery respectively. Atretic left arch from which left innominate artery is arising which further branches into left common carotid and left subclavian artery.Descending aorta is seen on left side. Small aneurysmal like outpouching measuring approx 4.3mm in diameter and 4.2 mm in length is seen at right aortic arch and descending aorta junction, projecting anteriorly, suggestive of kommerell diverticulum. This diverticulum is residual distal segment of left arch.Note is made of small residual pouch of treacheo-oesophagal fistula at posterior wall of trachea just before bifurcation.Small consolidatory changes at right middle lobe.Imaging features are suggestive of an incomplete double aortic arch and kommerell diverticulum with trachea positioned inside the ring.Note is also made of almost symmetrical subcutaneous soft tissue enhancement of both upper chest walls, consistent with brown fat enhancement (normally seen on CT angiograms of neonates).Pectus excavatum is also noted.

Response: In the left flank there is an extensive area of mixed fluid and gas density extending over approximately 18 cm in a craniocaudal direction.Following discussion with the clinical team and review of the operation note it was determined that Surgicel material was left in place below the spleen which accounts for this appearance rather than a faeculent collection.

Swirling of the superior mesenteric vessles is noted with "whirl sign" of the tightly twisted mesentery. The distal bowel loops are seen collapsed.Mild amount of abdominal and pelvic fluid collection is noted.The prostate is mildly enlarged with intact prostatic capsule as well as homogeneous parenchyma with small prostatic concretions.Spondylotic changes of the dorsolumbar spine with 1st degree degenerative anterolisthesis L4 over L5.

Response: Large right adrenal mass lesion. This lesion is relatively well demarcated and abuts the posterior margin of the IVC, medial margin of the liver and lateral margin of right hemidiaphragm crura. There is no evidence of local invasion.The more prominently enhancing posterosuperior component measures 29 HU on non-contrast, 84 HU on portal venous and 43 HU on delayed phase - calculating to 74% absolute washout and 49% relative washout. The anterior component has less prominent enhancement and measures 35 HU on non-contrast, 59 HU on portal venous and 43 HU on delayed - calculating to 66% absolute washout and 27% relative washout.Normal left adrenal gland.

Response: Hypoperfusion of the left kidney with patchy areas of delayed enhancement. The excretory phase shows no pelvicalyceal or ureteric contrast excretion. On the arterial phase, despite opacification of the intrarenal branches, the renal artery appears irregular with a proximal intraluminal linear filling defect - dissection? The left renal vein is probably opacified by retrograde filling from the IVC. Features of AAST grade V renal injury - traumatic renal vascular injury with devascularization of the kidney.Small perivascular and perinephric hematomas.AAST grade III splenic injury.Subcapsular hemangioma in hepatic segment 7.

Response: Because of a Valsalva manoeuvre during the image acquisition, contrast has refluxed in the venous circulation, causing particularly prominent opacification of a vein connecting the accessory hemiazygos vein to the left brachiocephalic vein. This vein is the left superior intercostal vein, which gives the radiographic image of an "aortic nipple". The azygos vein is not seen except in its arch, most likely hypoplastic with compensatory enlargement of the hemiazygos drainage system.

Response: There is a large lobulated heterogenous non-calcified soft tissue mass in the left kidney. The mass measures approximately 9.2 x 7.4 x 10.2 cm (AP x T x L). It shows arterial vascular supply. There are areas of non-enhancement suggestive of necrosis or cystic components. There is no extension of the mass behind the aorta. The upper portion of the mass reaches the midline. The left ureter is displaced medially but shows no wall thickening or filling defect.The adjacent bowel loops are displaced. The pancreatic tail is effaced and also displaced towards the right. The mass abuts and partially effaces the adjacent psoas muscle.The left renal vein and suprarenal inferior vena cava are expanded with a filling defect indicative of tumour thrombosis.  Filling defects, likely thrombi, are also seen in the infrarenal inferior vena cava and bilateral iliac veins. A round non-enhancing hypodensity, likely a cyst measuring 1.9 x 1.0 cm (AP x T), is seen in the right kidney. The right ureter is unremarkable.

No gross pathology is appreciable in the non-prepared colon.  A well-defined soft tissue density nodule measuring approximately 2.5 x 2.9 cm (average density= 30 HU on plain scan) is noted in the right adrenal gland. The morphology of the remaining abdominal viscera is unremarkable. No significant abdominopelvic lymphadenopathy is seen.Based on these CT scan features (diffuse circumferential thickening of second part of the duodenum and proximal/mid jejunal loop with mild fat stranding around these affected bowel segments); differential diagnosis of inflammatory bowel disease (Crohn disease),  tuberculosis, or lymphoma was given. Small right adrenal nodule, was likely an incidental benign finding (e.g. lipid poor adenoma), as the patient did not have any clinical or biochemical evidence of adrenal dysfunction.

Response: The 30 x 40 mm mass located above the right petrous apex, involving Meckel's cave, is inseparable from the postero-lateral margin of the clivus, and has coarse central calcifications. There is local destruction of cortex. Note that the right supraclinoid internal carotid artery has a close relationship to the mass, and that the right posterior cerebral artery is almost entirely fetal origin, the branch displaced by and covered by the mass. Extracranial vessels are normal. No significant stenosis. No intracranial aneurysm or vascular malformation. Conclusion: The additional information from the CT study effectively excludes neurofibroma or meningioma. Either chondrosarcoma or less likely chordoma.
