Cervical stenosis. There is extensive ossification of the posterior longitudinal ligament from C4 to T1 with mild compression of the spinal cord at C3-4 to C4-5, but there is no discernible spinal cord signal abnormality. There is also mild indentation of the anterior aspect od the spinal cord at the C6-7 level, but the posterior thecal sac cerebrospinal fluid space is maintained at this level. There are lesser degrees of spinal canal narrowing at the other levels. There is an anterior osteophyte that bridges the C5-6 disc space, which suggests a limited manifestation of DISH. There are small disc-osteophyte complexes at C6-7, C7-T1, and T1-2, with up to mild neural foraminal narrowing at these levels. There is no evidence of bone marrow edema. There is no spondylolisthesis. The vertebral body heights are preserved. The imaged paraspinal soft tissues and intracranial structures are unremarkable.
