Response: Changes of previous biliopancreatic diversion surgery are seen. Dilated oral contrast filled jejunal loops measuring 3-4 cm are seen in the left lumbar region. No oral contrast passage is seen in the distal small bowel. Mildly dilated fluid-filled ileal loops are seen clustered in the right lumbar region. Two distinct transition points located next to each other, mesenteric edema/inter-loop fluid, and a whirl sign are appreciable along these dilated ileal loops in the right lumbar region.  No pneumatosis or pneumoperitoneum is seen. A small amount of free fluid is seen around the liver. No oral contrast leakage/extravasation is seen. A hyperdense focus is seen in supra-renal abdominal inferior vena cava (inferior vena cava filter with probable surrounding thrombus). Enlarged azygous vein and multiple collaterals are seen in the abdominal cavity as well as in the subcutaneous soft tissues of the abdominal wall; these findings are suggestive of chronic inferior vena cava thrombosis (likely as a complication of IVC filter or a complication of previous bariatric surgery). Average size kidneys with multiple peripheral small subcentimeter hyperdense cysts (average density=70-90 HU), which are likely hemorrhagic cysts (hyperdense renal cysts). A simple cortical cyst is also seen in either kidney. CONCLUSION: The above mentioned CT findings are suggestive of closed-loop small bowel obstruction secondary to internal hernia (related to previous surgical interventions); another possibility can be adhesions. The possibility of small bowel ischemia cannot be excluded from this unenhanced examination (IV contrast not administered due to high creatinine).

Response: Large soft tissue mass, leading to the destruction of more than 50% of the volume of C2-C3 vertebrae, mainly on the right side. The soft-tissue mass spreads to the right parts of the spinal canal, pushing aside and compressing the dural sac.CT angiography was requested to assess the vertebral artery, the boundaries and the possible source of blood supply to a tumour. A large mass with clear contours is determined, with the presence of an extensive pathological vascular network supplied by the branches of a. cervicalis profunda and a. cervicalis ascendens on both sides. Venous outflow is probably via vv. cervicalis profundae.CT scan of the abdomen in the delayed phase after angiography revealed a large tumour of the right kidney with signs of pathological vascular venous mets along the upper pole with probable soft tissue focus of bony destruction in the body of the right ilium.The remaining bones at the studied levels are without destructive changes. There are no visible liver metastases. CT scan of the lungs without focal changes (not shown).

Response: There is a very large mass involving the pancreas tail which is invading and surrounding several adjacent structures. Most notably for the patient's presentation, it is obstructing and invading into the colon at the splenic flexure, with upstream moderate to severe colonic dilation and some distal small bowel dilation as well. Additionally, it is surrounding the left adrenal gland and extending into the left renal hilum, and obstructing the left renal vein and also encasing and narrowing the left renal artery, resulting in some left renal enlargement and delayed enhancement and also isolated calyceal dilation in the left upper renal pole. There are left periureteric varices and a few smaller retroperitoneal varices likely accounting for collateralized kidney drainage. This mass is also obstructing the splenic vein resulting in upper abdominal/short gastric collaterals. There is a component of soft tissue extending about the mid abdominal aorta as well. Borderline upper abdominal lymph nodes. Extensive and infiltrative metastases involving the liver, most pronounced within the left hepatic lobe.

Response: Hepatic steatosis. Dilated duodenum with oral contrast, which compresses the IVC. Clockwise twisting at the duodenal-jejunal junction about 360 degrees, resulting in luminal narrowing but no obstruction as contrast has passed distally. Adjacent minimal fluid/stranding and mildly congested mesenteric nodes. A large SMV varix bypasses the resultant venous narrowing, meandering through the right abdomen. Redundant but normally positioned large bowel.

Response: Ulcerated lesion involving the left posterolateral tongue and measures 2.7 centimetres in AP and 2.5 centimetres in craniocaudal dimension at the depth of 12 mm. No further sites of asymmetric mucosal thickening in the aerodigestive tract.13 x 9 x 8 mm left jugulogastric lymph node has an apparent hypodense component, however this is confirmed on axial images to be beam hardening artefact rather than a real finding. Left level II B lymph node is mildly prominent measuring 5.5 x 10 x 10 mm. No enlarged submental or submandibular lymph nodes.Edentulous mandible and maxilla. No osseous destruction.The canal for the left inferior alveolar nerve is expanded with intact sclerotic rim suggesting a benign process. There is no permeative lucency in the surrounding mandibular body to suggest an aggressive process, and this region is separate from the tongue primary.No mediastinal or hilar lymph node enlargement. No pleural effusion. No suspicious pulmonary nodule or mass.Conclusion:2.7 centimetres a left posterolateral tongue lesion measures 12 mm in depth.Expanded canal for the left inferior alveolar nerve has non-aggressive CT appearances is not thought to be due to perineural spread of tumour.
