Aicardi syndrome: postmortem findings.

A 2-month-old infant with the typical clinical features of Aicardi syndrome (i.e., infantile spasms, chorioretinal lacunae, and agenesis of the corpus callosum) is reported. At 5 years of age, pathologic examination revealed cortical heterotopias, rostral agenesis of the corpus callosum, hypoplasia of the unilateral optic nerve, and bilateral cerebellar hemispheres. Cavum septum pellucidum was present. A literature review of 5 autopsied patients with this syndrome is included.
