Three-dimensional ultrasound evaluation of short-rib polydactyly syndrome type II in the second trimester: a case report.

Prenatal diagnosis of short-rib polydactyly syndrome is possible and has been reported in literature, but a precise ultrasound diagnosis is not easy. We report a case in which three-dimensional ultrasound was used in the evaluation of the disorder. The contribution and potential application of three-dimensional sonography in the prenatal diagnosis of short-rib polydactyly syndrome and other fetal skeletal malformations is discussed.
