Coronary Aneurysms in a Young Adult: Report of a Case Suspected of Kawasaki Disease

Abstract

An autopsy case of coronary aneurysm was reported. The patient, a 23-year-old Japanese man, suddenly fell unconscious during a karate match and died an hour later. The autopsy revealed coronary aneurysms, one of which was accompanied by thrombosis. Histologically, the aneurysmal walls showed marked scar formation and intimal thickening and the state was regarded as healed arteritis. By taking a precise history from his parents, Kawasaki disease was thought to be the probable cause of the coronary aneurysms.
