Early prenatal diagnosis of short rib-polydactyly (SRP) syndrome type I (Majewski) by ultrasound in a case at risk.

Short rib-polydactyly (SRP) syndrome Type I was diagnosed accurately in an at-risk fetus at 16 weeks of gestation by real-time sonography. The most important findings were a narrow thorax, significant shortening of the long bones, particularly the tibiae, and--by directed search--the polydactyly.
