Cerebral infarction after high-dose intravenous immunoglobulin therapy for Kawasaki disease.

A 3-year-old boy with Kawasaki disease developed a cerebral infarction after high-dose intravenous immunoglobulin. Aspirin did not prevent the stroke. Based on the numerous reports of thrombosis due to high-dose immunoglobulin in older individuals, we conclude that it is necessary to be aware of this complication when treating children with Kawasaki disease.
