Prenatal diagnosis of Jeune-like syndromes with two-dimensional and three-dimensional sonography

The purpose of this article is to describe the use of three-dimensional sonography as an adjuvant to two-dimensional sonography facilitating an earlier and more definitive diagnosis of Jeune and Jeune-like syndromes in the second trimester. We report two cases in which three-dimensional sonography facilitated the diagnosis of these malformations. A diagnosis of Jeune syndrome was made in our first case. Our second case was found to be short-rib polydactyly syndrome Type IV. Three-dimensional skeletal survey visualized short ribs, short limbs, the presence of normal scapulae, and the absence of polydactyly in both cases. Three-dimensional sonography can assist two-dimensional sonography in providing a more accurate display of skeletal anomalies, limb abnormalities, and facial features.
