Three‐dimensional ultrasound in diagnosing phocomelia

Abstract

Deformations of the extremities with limb reduction are rare congenital defects which affect one in 1692 live babies. Three‐dimensional ultrasound can be of value in the prenatal diagnosis of such deformities. We present a case of upper phocomelia and congenital thrombocytopenia (TAR syndrome). Visualization of the upper extremities was achieved by three‐dimensional ultrasound after surface and volume rendering. This new technique allows imaging not only of surfaces like the fetal skin, but also of internal structures like the fetal skeleton.
