Cervical canal stenosis caused by progressive fusion and enlargement of cervical vertebrae with features of Proteus syndrome and Klippel-Feil syndrome.

[proteus syndrome]

We report the case of a female who presented with progressive fusion and an enlargement of the cervical vertebrae . Her cervical deformity gradually progressed with age , and the abnormal bony protrusion into the spinal canal caused myelopathy . We resected the affected vertebrae to decompress the spinal cord and performed combined anterior -posterior spinal fusion . The progression of the spinal deformity and enlargement of vertebrae stopped after surgery . The enlargement of vertebrae in the present case resembled that observed in Proteus syndrome ; however , autonomous vertebral fusion has not been reported previously in patients with this condition . Our report may help expand the knowledge on developmental spine disorders .
