Prenatal diagnosis of thrombocytopenia-absent radius syndrome

The prenatal diagnosis of thrombocytopenia-absent radius (TAR) syndrome by ultrasound is established. The sonographic findings showed bilateral absence of the radii and club hands with normal thumbs and metacarpals. Thrombocytopenia was identified from the postabortal cord blood. Three-dimensional computerized tomography images confirmed the sonographic diagnosis. This report, to our knowledge, is one of the few cases published in the literature about the prenatal diagnosis of TAR syndrome.
