Abstract

Hemimegalencephaly is a rare brain malformation characterized by congenital hypertrophy of one cerebral hemisphere with ipsilateral increased volume of the white matter and dilatation of the lateral ventricle. We have experienced two cases of hemimegalencephaly in neonates who were admitted because of repetitive seizure. One case was simple hemimegalencephaly and the other case was combined by corpus callosum agenesis. Diagnosis was made by CT and MRI. A brief review of literature was made.
