Persistance et hyperplasie du vitré primitif et syndrome d’Aicardi

[Aicardi syndrome associated with severe congenital ptosis]

Aicardi syndrome is a rare neurodevelopmental disorder characterized by corpus callosum agenesis, chorioretinal lacunae and early-onset infantile spasms. We report a particular case of Aicardi syndrome characterized by the association of the classical triad of severe bilateral ptosis, pontocerebellar hypoplasia, and perisylvian polymicrogyria in a girl born to non-consanguineous parents, but whose mother suffered from idiopathic generalized epilepsy.

Prenatal ultrasonographic diagnosis of persistent hyperplastic primary vitreous

Persistent hyperplastic primary vitreous (PHPV) is a rare developmental malformation of the eye characterized by the presence of a vascular membrane located behind the lens. We report, for the first time in the literature, the identification on ultrasound examination of bilateral cataract and thickened hyaloid artery-lens junction, leading to a diagnosis of bilateral PHPV, in a fetus at 23 weeks' gestation. Histological examination at postmortem confirmed the prenatal diagnosis of bilateral PHPV and cataract. A thorough ultrasound examination of the fetal eye in cases with cataract is recommended.
