Cervical radiculopathy due to disc herniation with adjacent facet hypertrophy: case report.
We report a rare case of cervical radiculopathy associated with facet hypertrophy and disc herniation. The patient was a 38-year-old woman with sudden-onset left arm pain. As conservative therapy failed to alleviate her symptoms she was referred to us. On physical examination she manifested no neurological deficits except pain and dysesthesia in the left C7 territory. Computed tomography revealed hypertrophic ossified changes in the left T1 facet joint with encroachment on the spinal canal. Magnetic resonance imaging showed compression of the spinal cord at C6/7 by disc herniation at C6/7. Anterior cervical decompression and fusion by corpectomy (C7 corpectomy and C6/T1 fixation with a titanium cage) ameliorated her pain. Facet hypertrophy in a morphologically normal cervicothoracic spine is extremely rare and its etiology is unknown. We speculate the possibility that our patient harbored a congenital anomaly and that the morphologic changes were the consequence of an injury she sustained in a traffic accident.
