History of colon cancer now with PET avid lesion in the liver. Evaluate metastatic disease. ABDOMEN:LIVER, BILIARY TRACT: Borderline hepatomegaly with the liver measuring 17 cm in length. There is diffuse hepatic parenchymal signal loss in the out of phase images compatible with hepatic steatosis. The extrahepatic portal vein is occluded and there is cavernous transformation of the portal venous system. The hepatic veins and hepatic arteries are patent.There is patchy minimally increased T2 signal in the right hepatic lobe at the site of increased FDG activity seen on prior PET. This is not associated with restricted diffusion. There is mildly heterogeneous postcontrast enhancement throughout the liver likely secondary to the altered hemodynamics from portal venous occlusion. No suspicious masslike enhancement.Status post cholecystectomy. Scattered areas of minimal intrahepatic biliary ductal dilatation including in the right hepatic lobe at the region of interest.SPLEEN: No significant abnormality noted.PANCREAS: Postsurgical changes related to prior Whipple procedure. Stable minimal prominence of the distal pancreatic duct.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Numerous bilateral simple cysts.RETROPERITONEUM, LYMPH NODES: No retroperitoneal lymphadenopathy. Unchanged mildly prominent mesenteric lymph node in the right upper quadrant.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Hepatic steatosis and borderline hepatomegaly. There is heterogeneous signal throughout the liver likely related to the altered hemodynamics from portal vein occlusion. No definite enhancing mass lesion to indicate metastatic disease.2.Stable mildly prominent right upper quadrant mesenteric lymph node.3.Postoperative changes from prior Whipple with stable mild prominence of the distal pancreatic duct.
