We report a case of large pancreatic duodenal artery aneurysm with fistula formation to superior mesenteric vein (SMV), which was successfully treated by coil embolization. This patient had a history of surgery for pancreatic pseudocyst approximately 30 years earlier, that might have been related to the arteriovenous fistula formation. Coil embolization was successfully per-formed for the aneurysm with the arteriovenous fistula to SMV. After the embolization, SMV thrombosis was temporarily observed but disappeared one month later on enhanced CT.
