Cervical stenosis, arm weakness Again seen are postsurgical changes of anterior cervical fusion from C4-C5. There is solid osseous fusion. There is also evidence of laminectomy from C3 to C6. Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate height. Alignment is maintained. No suspicious osseous lesions. The cervical spinal cord has normal signal characteristics and overall morphology.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: Small disk osteophyte complex. No significant spinal canal stenosis. There is moderate to severe right and mild left neural foramina stenosis.C4-5: Minimal left neural foraminal narrowing. No significant compromise to the spinal canal or right neural foramina.C5-6: There is diminished disk height and disk osteophyte complex with minimal effacement of the ventral thecal sac. Ligamentum flavum thickening also seen with partial dorsal thecal sac effacement. Minimal spinal canal stenosis. There is moderate to severe left neural foramina stenosis. Artifact makes evaluation difficult. There is some low ill-defined T2 signal in the right neural foramen which may be related to scar tissue if there has been a foraminotomy or possibly extruded disk material. There is also bilateral uncovertebral hypertrophy. CT may be helpful to assess the surrounding bony anatomy given hardware artifact.C6-7: There is diminished disk height and small disk osteophyte complex eccentric to the right. There is extruded disk material effacing the left ventral aspect of the thecal sac and narrowing the left neural foramen which appears to be present on prior study but better visualized on the current study. There is mild right neural foramina 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.
1. Postsurgical changes of anterior cervical fusion at C4-C5 as well as posterior decompression with laminectomies from C3 to C6. 2. Multilevel degenerative changes including narrowing of the right C5-C6 neural foramen which may represent disk material or possibly scar tissue if there has been a foraminotomy (axial T2 23-24/39). Artifact related to the hardware makes evaluation difficult and CT may be helpful to better define the bony anatomy. There is also moderate to severe right C3-C4 and mild right C6-C7 neural foraminal stenosis. 3. Additional levels of neural foraminal narrowing as detailed above. No significant spinal canal stenosis or cord signal abnormality.
