Schizencephaly is an uncommon congenital structural disorder of cerebral cortex caused by abnormal neuronal migration. Patients usually present with seizure disorders, hemiparesis, quadriparesis, cognitive deficits and mental troubles. Very rarely, schizencephaly is also associated with subdural fluid collection, and may present with mass effect. In this study we present a schizencephaly case with chronic subdural fluid collection. In our view, clefts may promote subdural fluid collection in schizencephaly patients and careful follow up of these patients is needed.
