Hemispherectomy is recommended in cases of hemimegalencephaly with frequent and resistant seizures. The clinical EEG and neuroimaging data of 14 patients was analyzed. Seven patients had intractable seizures several times per day (Group A), seven had sporadic and intractable seizures (Group B). Group A, candidate for hemispherectomy, differed from Group B as follows: earlier onset of seizures, peculiar ictal semeiology and EEG pattern, more serious damage in the cerebral cortex and greater developmental differences between malformed and healthy hemisphere.
