A rare case of schizencephaly in an adult with late presentation.

Schizencephaly, i.e., split brain, is a rare, congenital cerebral malformation. Magnetic resonance imaging is the best neuroimaging modality for its diagnosis. In literature, only few cases have been reported causing symptoms in adults. Symptomatic patients present as hemiparesis, developmental deficits to seizures. This condition is usually found at birth and presents during early years. Appropriate diagnosis of the disease is necessary to avoid incorrect treatment. Here, we present a rare case of left, unilateral, open lip schizencephaly in an adult patient presenting with partial seizures but with an asymptomatic childhood.
