Nonspecific biliary dilation of the common bile duct noted on ultrasound. History of hepatitis C. ABDOMEN:LIVER, BILIARY TRACT: Subcentimeter liver cysts. A subcentimeter arterially enhancing T2 hyperintense lesion in the inferior left hepatic lobe (series 11, image 52) likely represents an hemangioma. A nonenhancing T2 hyperintense lesion in the right hepatic lobe (series 11, image 62) is indeterminant though likely of benign etiology. The common bile duct is prominent up to the level of the ampulla. No definite ampullary mass is identified. No intrahepatic biliary ductal dilation is present.SPLEEN: No significant abnormality noted.PANCREAS: The pancreatic duct is prominent up to the level of the ampulla. The pancreas is of normal signal and enhancement, without pancreatic mass identified.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Bilateral renal cysts, some of which are hemorrhagic. Otherwise no abnormality noted.RETROPERITONEUM, LYMPH NODES: A peripancreatic retroperitoneal lobulated nodule measures 2.5 x 2.3 cm (series 4, image 20), likely representing an enlarged lymph node. An additional enlarged portocaval lymph node is identified (series 4, image 21).BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.
Prominent common bile duct and pancreatic duct up to the level of the ampulla. Enlarged retroperitoneal lymph nodes. Although a definite ampullary mass is not identified on MR, ERCP is may be helpful for further evaluation given these findings.
