44-year-old man with history of abdominal pain and elevated bilirubin. ABDOMEN:LIVER, BILIARY TRACT: The liver is nodular in contour and there is prominence of the hepatic fissures. The intrahepatic biliary ducts are irregularly dilated up to 9 mm, worse in the left hepatic lobe and with areas of stricturing such as that seen at the confluence of the medial and lateral branches of the left hepatic duct (series 601, image 29). There is no area of restricted diffusion or abnormal signal to suggest a mass.The extrahepatic biliary duct is also irregularly dilated and the common bile duct measures up to 11 mm in maximal diameter. The common bile duct is seen tapering distally without evidence of mass lesion.An apparent filling defect seen in the mid common bile duct (series 601, image 23) is not seen on the other sequences and thus considered less likely to represent choledocholithiasis, appearance is similar to prior outside MRI.SPLEEN: The spleen appears normal. Numerous perisplenic varices are noted.PANCREAS: The pancreas appears normal.ADRENAL GLANDS: The adrenal glands appear normal.KIDNEYS, URETERS: An 8 mm right mid pole renal cyst is seen along with additional subcentimeter renal cysts bilaterally.RETROPERITONEUM, LYMPH NODES: No significant lymphadenopathy noted.BOWEL, MESENTERY: The partially visualized small bowel and colon appear normal. There is no evidence of colonic wall thickening or loss of haustral pattern.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Findings of PSC and cirrhotic liver without lesion suspicious for cholangiocarcinoma.
