title: Congenital bilateral perisylvian polymicrogyria presenting as congenital hemiplegia.
abstract: We report three children with pure congenital hemiplegia found to have congenital bilateral perisylvian polymicrogyria (CBPP). None of our patients had the seizures, oromotor dysfunction, or cognitive impairment usually associated with CBPP. CBPP may be more common and heterogeneous than previously thought, is easily recognized by MRI, and should be included in the differential diagnosis of the young child presenting with congenital hemiplegia.
