Autopsy Case of Acute Myocardial Infarction with Large Vessel Arteritis

Abstract

Microscopic polyangiitis (MPA) is characterized by the inflammation of small-sized vessels. We describe a patient with MPA who had suffered large vessel arteritis. A 94-year-old woman who had been given a diagnosis of MPA suffered abdominal aortic aneurysm. This case presented with prolonged fever and aggressive inflammatory reaction and the diagnosis was made during the early phase. An autopsy revealed the systemic vasculitis.
