Abnormal spinal curvature in the fetus.

We reviewed 20 cases of sonographically detected abnormal fetal spinal curvature to help determine the significance of this finding. Both marked (13 cases) and mild (7 cases) curves were diagnosed sonographically. Sonography showed associated anomalies in 19 fetuses, including neural tube and ventral wall defects. Outcomes were poor, with only three infants surviving. Isolated scoliosis was identified prenatally in one neurologically normal infant with hemivertebrae. We conclude that abnormal spinal curvature in the fetus is a significant finding, whether mild or severe. Even as an isolated finding, it is significant, as prenatal detection assists postnatal management.
