OBJECTIVE: To show the disorders of the brain cortical development and the possible origin in base to a large series studied in a Pediatric Neurology service. PATIENTS AND METHODS: A series of 144 children with ages ranging between newborn and 12 years was studied from the clinic, image (MR, 3DMR) and evolutive point of views. RESULTS: The diagnosis was: polymicrogyria in 61 cases, lissencephaly in 22, eschizencephaly in 16, heterotopia in 16, cortical dysplasia in 9, hemimegalencephaly in 8, cobblestone in 7, sublobar dysplasia in 3, and 'double cortex' in 2. Mental retardation, motor disorders and epilepsy were the most important anomalies. CONCLUSIONS: Actually, the image is the most important study to make the diagnosis of every type of cerebral malformation. However, to know the specific gene that origin every disorder seems to be the most important thing to make the classification of every malformative type and the possible prevention of this pathology.
