Dorsolumbar spine duplication.

We report a case of dorsolumbar spine duplication in a female patient. She had several vertebral anomalies, such as fused vertebrae, hemivertebrae and butterfly vertebrae, together with duplication of the spinal column in the lower thoracic and the whole lumbar tract. Clinically, she had no control of the sphincters, but her gait was only slightly affected. This is probably the third reported case of this rare anomaly.
