Arterial pseudoaneurysm is rare but potentially a catastrophic complication of pancreatitis because it can cause massive gastrointestinal bleeding. Since surgical treatment of arterial pseudoaneurysm has a high mortality, percutaneous angiographic embolization of bleeding artery has recently been advocated as the alternative therapy. Acute hemorrhage into the peritoneal cavity or pseudocyst complicating chronic pancreatitis was frequently reported. However, multiple pseudoaneurysmal hemorrhage without pseudocyst complicating acute pancreatitis are extremely rare. Here, we present a case of multiple pseudoaneurysmal hemorrhage secondary to acute pancreatitis, which were managed successfully by percutaneous angiographic embolization.
