Detailed ultrasonographic findings in Greenberg dysplasia.

A case of Greenberg dysplasia [hydrops fetalis, ectopic calcifications, "moth-eaten" skeletal dysplasia (HEM)] is presented. Fetal ultrasonography at 20 weeks' gestation showed hydrops fetalis, severe micromelia, irregular hyperechogenic foci in the ribs and vertebral bodies, irregular hypo- and hyperechogenic areas and abnormal contour within the long bones, and flattened and "T"-shaped appearance of the vertebrae. Findings on postmortem histological and radiographic examination were consistent with Greenberg dysplasia.
