A 60-year-old man presented with icterus and stomachache. Enhanced CT showed dilatation of both the main pancreatic duct and bile duct, enhanced wall thickening in the lower bile duct, and minute linear calcification along the pancreatic duct in the pancreatic head. ERCP showed redness of the main papilla and bile duct-duodenum fistula. Biopsy of papilla and fistula did not reveal malignancy. FDG-PET showed strong accumulation in the pancreatic head. Because malignant disease of the lower bile duct or pancreatic head could not be denied, we performed pylorus-preserving pancreatoduodenectomy though the tumor markers were not elevated. A pathologic diagnosis of pancreatic abscess caused by actinomycosis was estalished. Actinomycosis in the pancreas is extremely rare. The fistulous opening of the bile duct to the duodenum may be one cause.
