Dense ossification of the posterior longitudinal ligament results in severe canal stenosis from C2-4. From C4/5 to C6/7 the ossification is less dense and predominantly midline resulting in anterior indentation of the thecal sac.

Extensive low signal ossification of the posterior longitudinal ligament (OPLL) with moderate to severe central canal stenosis, particularly at C4-5 and C5-6. Straightening of the cervical lordosis. Minor increased T2 cord signal in keeping with myelopathy.
