Pancreatic arteriovenous malformation (AVM) is a relatively rare disease. Based on our literature search, 51 cases of pancreatic AVM have been reported since 1968. The gastrointestinal bleeding is the most common presenting symptom (24/51 cases [47%]). There were only 6 cases of pancreatitis in these cases. We describe 2 cases of acute pancretitis with pancreatic AVM. The patients who were diagnosed with acute pancreatitis were admitted to our hospital. Pancreatitis was considered to be caused by pancreatic AVM by some modalities of diagnostic imaging. The respective pancreatic AVM lesions of patients were resected to prevent the recurrence of pancreatitis. They are asymptomatic after the surgery. Pancreatic AVM is thought to be the one of the reasons for acute pancreatitis.
