Degenerative disease of the cervical spine Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. There is straightening of the cervical spinal curvature and minimal retrolisthesis at the C5-C6 level. Alignment is otherwise maintained. Bone marrow signal is benign.There is susceptibility effect related to interbody graft at the C5-C6 level which obscure the ventral thecal sac on the sagittal images. The cervical spinal cord has grossly normal signal characteristics and overall morphology with apparent T2 hyperintensity at the C5-C6 level which is likely artifactual.Mild degenerative changes are seen in the cervical spine including mild multilevel facet arthropathy in the cervical spine and visualized upper thoracic spine. Individual levels 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: Small disc osteophyte complex and mild bilateral uncovertebral hypertrophy. No significant spinal canal or neural foraminal stenosis.C5-6: Disc prosthesis with associated susceptibly artifact slightly limiting evaluation. There is uncovertebral hypertrophy. Mild right-sided neural foraminal stenosis. No significant spinal canal or left neural foraminal stenosis. C6-7: There is a disc bulge and annular fissure. There is moderate narrowing of the left neural foramen related primarily to the disc bulge with small contribution of uncovertebral hypertrophy and left-sided facet arthropathy. There is no significant spinal canal or right neural foraminal stenosis.C7-T1: No significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.
Postsurgical changes at the C6-C7 level with susceptibility artifact from disc prosthesis slightly limiting evaluation of this level. Hardware position is better assessed on prior radiographs. Degenerative changes are seen with mild right C5-C6 and moderate left C6-C7 neural foraminal stenosis. No significant spinal canal stenosis at any level.
