A Case of Septo-Optic Dysplasia-Schizencephaly Complex

ABSTRACT

Septo-optic dysplasia is diagnosed when optic nerve hypoplasia is combined with dysgenesis of the septum pellucidum and nearly two-thirds of them have hypothalamic-pituitary dysfunction. A number of these patients have schizencephaly and usually present seizures. The migrational disorders including schizencephaly, lissencephaly, heterotopia and polymicrogyria are a rare group of congenital malformations of the brain Septo-optic dysplasia-schizencephaly complex is frequently associated with endocrinolo gic, ophthalmologic, and neurologic symptoms and signs. We recently experienced a case of septo-optic dysplasia-schizencephaly, who showed severe visual impairment associated nystagmus and bilateral optic nerve hypoplasia agenesis of septum pellucidum with schizencephaly and hypsarrythmia. Because some forms of migrational disorders and septo-optic dysplasia can be inherited, parental counseling is essential for the accurate diagnosis.
