Abstract

Multiple intrahepatic arterial aneurysms and spontaneous aneurysmal rupture associated with polyarteritis nodosa leading to hemoperitoneum are extremely rare occurrences, but the conditions can be life-threatening if left untreated because of the risk of massive hemorrhage. We report a case of a high-risk surgical patient with polyarteritis nodosa complicated by spontaneous rupture of multiple intrahepatic arterial aneurysms. He was initially treated with emergency gelatin sponge particle embolization, followed by maintenance steroid treatment. Complete resolution of intrahepatic arterial aneurysms was observed at follow-up.
