Schizencephaly as an Unusual Cause of Adult-Onset Epilepsy: A Case Report

Schizencephaly is a very rare anatomical malformation of the cerebrum characterized by a cleft extending from the cortex to the ventricles. Usually, this disease is diagnosed at a very young age or in early adulthood. Symptoms may vary depending on the site and the size of the malformation. Here, we are describing the unique case of a 21-year-old female, with a past medical history of migraine-type headaches, who presented after the first-onset seizure and was found to have open-lip schizencephaly. She was started on levetiracetam with no complications. In this report, we are trying to describe the proposed etiology and discuss the typical clinical presentation of schizencephaly and compare it to our adult patient who survived childhood without significant cognitive or neurological impairment.
