We report a case of an intrapancreatic accessory spleen indistinguishable preoperatively from nonfunctional islet cell tumor. A 53-year-old woman, treated for chronic hepatitis, was found to have a mass lesion in the tail of the pancreas in the early phase of the enhanced computed tomography. Abdominal ultrasonography showed a low-echoic mass 2 cm in diameter. Splenic arteriography showed a hypervascular stain fed by a branch of the great pancreatic artery. Endoscopic retrograde pancreatography showed a normal pancreatic duct. Duodenoscopy showed normal Vater papilla. Resection of the pancreatic tail and spleen showed accessory spleens in the tail of the pancreas.
