Progressive vertebral fusion of unknown etiology: a case report

We report a 16-year-old male with progressive vertebral fusion of the cervical, thoracic, and lumbar vertebrae; irregular vertebral body surfaces; coronal clefting of the vertebral bodies of the thoracic and lumbar spine; absence of one cervical vertebra; and a few other minor, nonspinous abnormalities. All laboratory findings have been within normal limits. To our knowledge, the particular findings in this patient have not been reported previously.
