A 60-year-old man undergoing pancreaticoduodenectomy for advanced pancreas head carcinoma suffered recurrence at the dorsal site of the remnant pancreas despite adjuvant chemotherapy. When he was hospitalized for hemorrhagic shock with hematemesis, abdominal computed tomography showed that the recurrent tumor had encased the splenic artery and a splenic artery pseudoaneurysm had perforated the stomach. The pseudoaneurysm was considered due splenic artery invasion by recurrent carcinoma and obstructive pancreatitis. The pseudoaneurysm was successfully treated by transcatheter arterial embolization and the man was discharged after one month. To our knowledge, splenic pseudoaneurysm perforating the stomach in carcinoma recurrence is extremely rare, with only 17 such cases reported in the Japanese literature.

Key words
