Seizure outcome after functional hemispherectomy for malformations of cortical development.
MRI features were correlated with postsurgical seizure outcome in patients with hemispheric malformations of cortical development (MCD). After functional hemispherectomy, 5 of 6 patients (83%) with hemimegalencephaly had persistent, although markedly improved, seizures; 5 of 6 patients (83%) with relative preservation of part of one lobe or atrophy were seizure free. Hemimegalencephaly and other types of hemispheric MCD appear to differ in prognosis for freedom from seizures after functional hemispherectomy.
