title: Polyarteritis nodosa presenting with splenic infarction, bilateral renal infarction, and hematoma.
abstract: Polyarteritis nodosa (PAN) is a necrotizing vasculitis and may affect multiple organ systems. Due to the rupture of microaneurysms, perirenal hematomas may occur in both kidneys. Spontaneous perirenal hematoma is an infrequent complication of isolated PAN. Also, involvement of the splenic arteries is a rare occurrence in polyarteritis nodosa. Perirenal hematoma rupture is a serious clinical condition. Patients with life-threatening visceral bleeding must be treated with a selective embolization procedure or radical surgery because nonoperative management has been associated with a significant mortality rate.
