Description

This article reviews Malformations of Cortical Development (MCD) diagnosed by Magnetic Resonance Imaging (MRI) in a series of patients with epilepsy. This study spans a five year period. The frequency of these malformations was 7.1%. Most of these were focal or multifocal and the most common ones were polymicrogyria (35.3% of the patients), heterotopia (29.4%), and focal cortical dysplasia (29.4%). The frontal lobes were the most frequently affected regions. The various MCD encountered reflect the wide spectrum of MCD leading to epilepsy.
