Neuronal migrational disorders of the brain represent abnormalities in the formation of the neocortex caused by faulty migration of the subependymal neuroblasts. These migrational anomalies include lissencephaly (agyria/pachygyria), pachygyria, schizencephaly, heterotopias, hemimegalencephaly, and polymicrogyria. We used MR imaging (performed on a 0.5-T or 1.5-T scanner) to evaluate 21 patients...

PURPOSE To correlate clinical outcome with the size and location of clefts in patients with schizencephaly. PATIENTS AND METHODS MR scans and clinical records of 20 patients with schizencephaly were retrospectively reviewed. Seven patients had bilateral clefts (10 open lip clefts, 4 closed lip clefts), eight patients had right-sided unilateral clefts (5 open lip clefts, 3 closed lip clefts), ...

A 45-year-old man without relevant family history presented with prune belly syndrome (PBS). He had a 34year history of right simple partial motor seizures with and without secondary generalization, with a good response to carbamazepine monotherapy; there was no cognitive or social impairment. MRI showed global brain atrophy, ventricular asymmetry, left hemisphere schizencephaly, and bihemisphe...

BACKGROUND AND PURPOSE Functional reorganization of the brain can result from congenital brain disorders as well as from brain infarction. The purpose of our study was to use functional MR imaging to determine whether reorganization of brain function occurs in patients with schizencephaly. METHODS Four patients with schizencephaly (three right-handed, one ambidextrous) presented with seizures...

This report attempts to document the potential of magnetic resonance (MR) tractography in providing detailed information on white matter tract anomalies in schizencephaly. Diffusion tensor imaging with tractography was performed in four patients referred for neuroimaging. On conventional MR imaging, two of the patients had temporal lobe involvement and the other two had frontal lobe involvement...
