Neck pain, status post posterior cervical spine surgery Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. Alignment is maintained. Bone marrow signal is benign. There is mild thickening and ossification along the posterior longitudinal ligament which is discontinuous are present from C4 to the C7-T1 levels. Bridging osteophytes ventrally are also noted which may be related to DISH but are relatively small. The cervical spinal cord has normal signal characteristics and overall morphology.Postsurgical changes are better assessed on recent CT including small laminotomies. Multilevel facet arthropathy including ankylosis of the left-sided facets noted on the left from C2 to C4.Degenerative changes are seen in the cervical spine as described below:C2-3: No significant compromise to the spinal canal or neural foramina.C3-4: No significant compromise to the spinal canal or neural foramina.C4-5: Ossification of the posterior longitudinal ligament and ligamentum flavum thickening result in mild spinal canal stenosis. There is moderate left and mild right neural foraminal stenosis.C5-6: Disc osteophyte complex is associated with mild spinal canal stenosis. There is moderate bilateral neural foraminal stenosis particularly involving the lateral aspect of the neural foramina.C6-7: Ossification of the posterior longitudinal ligament and mild ligamentum flavum thickening is associated with mild spinal canal stenosis. There is moderate to severe neural foraminal stenosis particularly involving the lateral aspect of the right neural foramen. No significant left neural foraminal narrowing.C7-T1: No significant compromise to the spinal canal. There is mild to moderate left neural foraminal stenosis. No significant right neural foraminal narrowing.The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.
Mild spinal canal stenosis at C4-C5, C5-C6, and C6-C7 related to disc osteophyte complexes and ossification of the posterior longitudinal ligament. There is also neural foraminal stenosis from C4-C5 to C7-T1 as detailed above. No cord signal abnormality.Postsurgical changes and ossification of the posterior longitudinal ligament better seen on recent CT.
