71-year-old male status post cholecystectomy now with recurrent acute pancreatitis and possible pancreatic mass ABDOMEN:LIVER, BILIARY TRACT: There is a mass at the Klatskin point, which demonstrates delayed retention of contrast and measures 1.9 x 1.8 cm (series 1305, image 45). Moderate bilobar intrahepatic biliary ductal dilation. Diffuse mild thickening of the left, right, and common hepatic bile ducts. Status post cholecystectomy. The common bile duct measures 10 mm in maximum diameter. Common bile duct stents.SPLEEN: No significant abnormality noted.PANCREAS: There is edema in the pancreatic head. No surrounding edema. Complex cystic mass at the pancreatic head / neck junction measures 2.7 x 2.6 mm (series 501, image 17) and communicates with the main pancreatic duct. The pancreatic duct is otherwise not dilated. There are small other cystic foci in the head.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Multiple right renal cysts.RETROPERITONEUM, LYMPH NODES: Nonspecific subcentimeter cardiophrenic lymph node. BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.
1.Enhancing hilar mass at the Klatskin point with associated intrahepatic bilobar biliary ductal dilation suspicious for cholangiocarcinoma. Mild thickening of the left, right, and common hepatic bile ducts; periductal tumor spread is not excluded.2.Pancreatic head edema compatible with acute pancreatitis. Complex cystic lesion at the pancreatic head/neck junction communicates with the main pancreatic duct and is most consistent with a pancreatic cystic neoplasm possibly a pseudocyst.
