Polyarteritis nodosa presenting with hemobilia and intestinal hemorrhage.

Polyarteritis nodosa is a multisystem disease primarily involving the small and medium-sized vessels. Prognosis depends on the presence and severity of visceral involvement. Thrombosis and aneurysm formation commonly occur in kidney and gastrointestinal tract. Although hepatic involvement is also common, hepatic aneurysmal rupture with intrahepatic or perihepatic hematoma formation is infrequent. Hemobilia secondary to aneurysmal rupture is a very rare condition. We present a case of polyarteritis nodosa accompanied by hemobilia and intestinal hemorrhage secondary to hepatic and mesenteric aneurysmal rupture.
