CONGENITAL BILATERAL PERISYLVIAN POLYMICROGYRIA PRESENTING AS CONGENITAL HEMIPLEGIA

We report three children with pure congenital hemiplegia found to have congenital bilateral perisylvian polymicrogyria (CBPP). None of our p atients had the seizures, oromotor dysfunction, or cognitive impairmen t usually associated with CBPP. CBPP may be more common and heterogene ous than previously thought, is easily recognized by MRI, and should b e included in the differential diagnosis of the young child presenting with congenital hemiplegia.
