Prenatal diagnosis of a short-rib-polydactylia syndrome type Saldino-Noonan at 17 weeks' gestation

A case is described in which the family history and the sonographic findings during the 17th gestational week led to the suspicion of a short-rib-polydactylia syndrome of the Saldino-Noonan type and an abortion was induced. The ultrasound image disclosed cystic structures in the topographic area of the kidney, marked ascites and oligohydramnios and indicated a severe fetal developmental disturbance.
