Abstract
|
|
|
We report a 5 year old girl who presented with a single episode of generalized tonic clonic seizure. Neurologic examination was normal. Psychologic evaluation and motor development of Denver developmental screening test were abnormal.
Electroencephalogram showed abnormalities on the both temporo parieto-occipital regions. Her-computer tomography scan showed abnormal hypodense white matter. The MRI revealed a bilateral layer of tissue that was iso-intense with gray matter,
between the
wall of the lateral ventricle and the cortex, extending from the frontal to the occipital region, and enlarged both occipital horns of the lateral ventricle. These image findings indicated band heterotopia, also known ′double cortex′which is a
kind of
neuronal migration disorder.
