Aicardi syndrome: more than meets the eye

An eight-month-old girl with infantile spasms and apparent blindness had electroencephalographic findings compatible with Aicardi syndrome. In addition to optic nerve hypoplasia, there were multiple congenital retinal malformations in the right eye, including chorioretinal lacunae, anomalous retinal vessels, posterior scleral ectasia, and a peripheral fibrous ridge. Magnetic resonance imaging demonstrated agenesis of the corpus callosum, absence of the septum pellucidum, optic nerve and chiasmal hypoplasia, pachygyria, cortical heterotopias, colpocephaly, and hypoplasia of the cerebellar vermis. This patient illustrates the broad spectrum of cerebroretinal malformations now known to characterize Aicardi syndrome.
