Cerebral infarction associated with Kearns-Sayre syndrome-related cardiomyopathy.

Abstract

We present the clinical and neuroradiologic findings of a 31-year-old man with Kearns-Sayre syndrome- related dilated cardiomyopathy who experienced a left middle cerebral artery territory stroke, thought to be due to cardiogenic embolism. The rate of clinically apparent cardiomyopathy in Kearns-Sayre patients can be expected to increase as their survival is prolonged by the use of cardiac pacemaker devices. Under these circumstances, stroke caused by cardiogenic embolism, which is presently rare, may become more common.
