Intraductal papillary-mucinous carcinoma (IPMC) coincidentally found with a pseudocyst at the hilum of the spleen: a case report

Abstract

A 71-year-old man, who had been followed-up for chronic alcoholic pancreatitis, was admitted to the hospital under the diagnosis of sternoclavicular arthritis. Chest X-ray revealed left pleural effusion. Computed tomography demonstrated a pancreatic pseudocyst at the hilum of the spleen. ERCP demonstrated a villous tumor at the duodenal papilla, and the pathohistology of the biopsy specimens revealed adenocarcinoma. The main pancreatic duct was remarkably dilatated at the pancreatic head, and an inner filling defect was observed. PPPD was performed, and intraductal papillary-mucinous carcinoma was diagnosed pathologically. When a pancreatic pseudocyst is observed, it is necessary to consider the possibility of pancreatic cancer and an intraductal papillary-mucinous tumor (IPMT).
