Early transvaginal ultrasonographic diagnosis of Beemer-Langer dysplasia: a report of two cases.

The early second-trimester sonographic diagnosis of two infants with short rib (polydactyly) dysplasia type IV (Beemer-Langer dysplasia) is presented. In addition to short ribs, this syndrome is characterized by short limbs with or without polydactyly. There are often associated defects, particularly neural-tube anomalies. The occurrence of consanguinity and of four affected siblings in this family support autosomal recessive inheritance.
