Introduction
Schizencephaly is a rare congenital brain malformation characterized by abnormal clefts in the cerebral cortex. Schizencephaly is rare and thought to affect 0.54 to 1.54 out of every 100,000 live births.1 1.48 per 100,000 live births is the estimated prevalence.2 Patients may present with seizures, developmental delay, and motor deficits. Absent septum pellucidum is a common association seen in patients with schizencephaly and has been reported to be present in up to 50% of cases.3Diagnosis is typically made through neuroimaging studies such as MRI. We report a 25-year-old adult who has an incidental diagnosis of schizencephaly with absent septum pellucidum.
