Celiac artery aneurysm associated with hemosuccus pancreaticus is extremely rare. We herein present a 67-year-old man with a large celiac artery aneurysm presenting with intermittent massive gastrointestinal bleeding due to connection of aneurysm with a blood-filled pancreatic duct who was successfully operated. To the best of our knowledge, this is the first report of a case of hemosuccus pancreaticus due to celiac artery trunk aneurysm.
