Prenatal ultrasound diagnosis of a rare occurrence of lethal multiple pterygium syndrome in two siblings

We report two cases of prenatal ultrasound diagnosis of the lethal form of multiple pterygium syndrome in successive pregnancies in the same woman. This extremely rare entity is characterized by multiple pterygia, flexion contractures, facial anomalies and hypoplasia of heart and lungs. The appearance of the congenital cataract is unique and this finding was present in both abortuses. Prenatal detection of this syndrome is feasible, and an ultrasound survey should be offered during genetic counselling to previously affected couples.
