Sudden Death in an Adolescent Four Years after Recovery from Mucocutaneous Lymph Node Syndrome (Kawasaki Disease)

Abstract

A case is presented of sudden death during physical activity in a 15-year-old boy with clinically inactive mucocutaneous lymph node syndrome (Kawasaki disease). At autopsy, the coronary arteries were involved by multiple aneurysms and obstructive thrombi, and the left ventricular myocardium was extensively scarred. Although Kawasaki disease most commonly occurs in infants and young children, it may be a cause of sudden death in adolescents.
