Polyhydramnios associated with fetal limb abnormalities.

Abstract

Four cases of fetal dwarfism and one case of extremity shortening with limb reduction abnormalities associated with polyhydramnios are presented. In one case, the diagnosis of camptomelic dwarfism associated with polyhydramnios was missed on sonography because no extremity measurements were obtained. Severe fetal limb anomalities were prospectively diagnosed in two patients with polyhydramnios by sonographic measurement of fetal limb lengths. The development of polyhydramnios was observed in two additional cases of fetal dwarfism. These five cases are presented to emphasize the clinical significance of recognizing the relationship between polyhydramnios and fetal dwarfism.
