A 54-year-old man presented with melena and was conservatively monitored for duodenitis. He developed epigastric pain, and dynamic computed tomography revealed abnormal blood flow in the pancreatic head. The endoscopic retrograde cholangiography revealed that the common bile and pancreatic ducts were simultaneously enhanced, thereby indicating the perforation of an arteriovenous malformation into both ducts. Despite medical treatment, the epigastric pain rapidly worsened and therefore, pancreatoduodenectomy was performed. The present report suggests that if the patient's general condition permits, surgical resection should be actively considered for the treatment of symptomatic pancreatic arteriovenous malformation.
