title: Hemobilia as presenting manifestation of polyarteritis nodosa.
abstract: Polyarteritis nodosa (PAN) is a multisystem necrotizing inflammatory vasculitis of medium-sized muscular arteries. Hepatobiliary complications secondary to thrombosis or aneurysm formation in PAN are rare and are associated with poor outcome. We describe an 18-year-old man with PAN who presented with hemobilia secondary to rupture of a hepatic artery aneurysm, which was successfully managed with coil embolization followed by immunosuppressive therapy.
