title: Prenatal diagnosed cyst of the quadrigeminal cistern in Aicardi syndrome.
abstract: Aicardi syndrome is an X-linked dominant disorder characterized by the pathognonomic association of three clinical signs: agenesis of the corpus callosum, infantile spasms, and chorioretinal lacunae. This is a severe syndrome with an estimated survival rate of 76% at 6 years and 40% at 14 years and a maximum developmental level like a 12-month-old baby in 91% of cases. We illustrate a case of Aicardi syndrome with bilateral, small chorioretinal lacunae, infantile spasms with a typical hypsarrhythmia, defects of thoracic vertebra and bilateral absence of the 12th rib associated with an arachnoid cyst of the quadrigeminal cistern, and presence of the corpus callosum with a favorable outcome.
