Abstract
Polyarteritis nodosa is a rare life-threatening disease characterized by necrotizing vasculitis of small and median arteries. We describe the exceptional case of a 28-year-old man with successive spontaneous visceral hematomas of the kidney, bladder, and liver. Arteriography was performed for a recent spontaneous hepatic hematoma and a microaneurysm was detected, allowing the diagnosis of polyarteritis nodosa and prescription of appropriate treatment.
