A 3-year-old girl was admitted with the complaints of abnormal eye movements and seizures. In fundoscopic examination, chorioretinal lacunae were detected in both eyes. A magnetic resonance imaging of the brain revealed agenesis of the corpus callosum and a mass obstructing third ventricule. Histopathological examination of the cystic lesion in the patient treated surgically demonstrated colloid cyst. Although good tolerance to intracranial cysts has been reported in Aicardi syndrome, the present patient with cystic lesion obstructing the third ventricle is herein discussed under the light of literature findings. © Gülhane Askeri Ti{dotless}p Akademisi 2010.trinfo:eu-repo/semantics/closedAccessAicardi syndromeVentricular cystArticle5216168Q4
