We report a case of recurrent acute pancreatitis caused by pedunculated tumor torsion at the duodenal papilla accompanied by abnormal pancreatic duct confluence. A 72 year-old man seeking emergency treatment for abdominal pain was diagnosed with acute pancreatitis. Upper gastrointestinal endoscopy showed pediculated tumor torsion at the duodenal papilla causing pancreatemphraxis and acute pancreatitis. Symptoms were relived when tumor torsion was released with forceps. Pancreatitis recurred due to same mechanism, however necessitating surgery. The duodenum was incised to extripate the tumor. The pathological tissue diagnosis was paraganglioma.
