Stripes of high echogenicity in the basal ganglia of infants have been rarely observed on cerebral ultrasound. These lesions, which appear to be due to a non calcific vasculopathy, are caused, in the majority of cases, by congenital infections and trisomy 13. We describe four infants with the characteristic ultrasonic appearance of this vasculopathy. Two children had cytomegalovirus (CMV) infection, one a human immunodeficiency virus (HIV) infection. The fourth child who presented a malformation of the skull and eye anomalies had no definitive diagnosis. Of the three surviving children one was developing normally. One had mild and one severe psychomotor retardation.
