Asymptomatic cerebral infarction in Kawasaki disease

Meningitis, facial palsy, subdural effusion, and cerebral infarction have been reported to be some of the nervous system complications of Kawasaki disease which usually are clinically obvious. A 22-month-old boy with Kawasaki disease, who developed asymptomatic cerebral infarction, is reported. Hyperpyrexia persisted for 57 days; echocardiography and magnetic resonance imaging revealed the presence of aneurysms in the coronary, axillary, and internal iliac arteries. This study indicates that patients with Kawasaki disease may have silent cerebral infarction.
