History of colon cancer with liver lesion. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in size morphology. Diffuse fatty infiltration with regions of focal sparing. There are several T2-weighted mildly hypointense lesions demonstrating restricted diffusion and heterogeneous postcontrast enhancement with central hypoenhancement, compatible with metastatic disease.A segment 2 peripheral lesion measures 2.7 x 2.0 cm (series 1 503/87).A segment 6/7 measures 2.8 x 1.9 cm (series 1 503/95).In segment 5 there is a peripheral wedge-shaped region of signal hyperintensity and abnormal enhancement with associated non-enhancing branching structures which likely represent occluded portal vein branches. No focal lesion at the apex of this abnormality is evident.Normally distended gallbladder without gallstones. 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: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: Incompletely evaluated dependent interstitial opacity in the lung bases may reflect atelectasis.
Bilobar liver lesions are compatible with metastatic disease.Basilar opacity may represent atelectasis/aspiration.
