MRI
Abnormal bone marrow signal is seen in the D1/D2 vertebral bodies displaying T1 hypointense and T2 hyperintense signals. This is associated with irregular opposing endplates, narrowing of D1/D2 disc with lacking a central nuclear cleft.
Intraspinal extradural linear soft tissue component extending from the D1/D2 level disc space compressing the thecal sac against the posterior neural arch and narrowing the neural exit foramina bilaterally.
Bilateral paravertebral soft tissue components also are seen.
Disco osteophyte bulging with thecal sac indentation is seen at C2/C3, C3/C4, and C5/C6 levels.
