Short rib polydactyly syndrome (SRPS) is a very rare congenital autosomal recessive inherited disease, classified into four subtypes. It has distinct imaging findings on prenatal sonography (US) and ancillary findings on both pre- and postnatal examinations may help classify individual cases into one of four subtypes. We report the US findings in a case of SRPS type IV (Beemer-Langer dysplasia) in a male fetus with multiple congenital anomalies, including cystic hygroma. The postnatal ultrasound, radiographic, and postmortem examinations helped to classify the SRPS as type IV. We believe this is the first documented case associating cystic hygroma and polydactyly. © 2009 Wiley Periodicals, Inc.
