They may arise in discrete cortical areas or involve widespread brain regions in one or both cerebral hemispheres. While extensive unilateral involvement of one cerebral hemisphere is a relatively uncommon condition, the rare occurrence of a hemispheric malformation is associated with a high rate of morbidity and mortality. Affected children typically manifest cognitive delay, intractable epileptic seizures, and lateralized neurological deficits.
