Female 62 years old Reason: 62F with colon CA. Suspicious lesions in liver on CT History: see above ABDOMEN:LIVER, BILIARY TRACT: There are 2 hypoenhancing lesions within the liver, one within segment 4A and the second within segment 8. These are difficult to identify on the axial T2 and diffusion-weighted images however on postcontrast images these demonstrate rim enhancement (series 1003, image 35). The largest lesion measures 0.6 x 0.5 cm (series 1003, image 35). The lesions do not meet criteria for hepatic cyst/hemangioma and are suspicious for hepatic metastases.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: Multiple enhancing, diffusion restricting retroperitoneal lymph nodes are suspicious for malignant involvement.BOWEL, MESENTERY: Circumferential thickening of an approximately 6.8 cm segment of distal transverse and proximal descending colon about the splenic flexure. There is abnormality of the adjacent mesentery likely due to a combination of direct extension from the colonic mass into the mesentery and an aggregate of matted regional lymph nodes. This confluent abnormality measures approximately 4.3 x 5.8 cm (series 1004, image 76). There is delayed enhancement of a peripheral thick rind of tissue surrounding the aforementioned colonic mass and mesenteric abnormality suggestive of a fibrous component of tumor which extends into the retroperitoneum to the left psoas muscle posteriorly (series 1004, image 74) and extends to proximal jejunal loops anteromedially (series 1004, image 71).BONES, SOFT TISSUES: No significant abnormality noted.
Circumferential colonic tumor at the splenic flexure with direct extension into the adjacent mesentery, mesenteric and retroperitoneal lymphadenopathy, and suspicion for hepatic metastases.
