Arm numbness and weakness, evaluate for cervical radiculopathy Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. There is loss of cervical lordosis; alignment is otherwise maintained. Bone marrow signal is benign. Postsurgical changes of posterior spinal decompression and cervical laminoplasty are seen from C3 to C7. Susceptibility artifact limits evaluation however no significant spinal canal stenosis at any level is appreciated. There is mild narrowing of the thecal sac caliber more diffusely from C3 to C6. There is abnormal T2 signal within the cord at the C4-C5 level which may represent myelomalacia from presumably prior compressive myelopathy.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: Spinal canal is surgically decompressed. There is moderate to severe right and moderate left neural foraminal stenosis.C4-5: Spinal canal is surgically decompressed. There is mild to moderate bilateral neural foraminal stenosis.C5-6: Spinal canal is surgically decompressed. There is moderate to severe left and moderate right neural foraminal stenosis.C6-7: Spinal canal is surgically decompressed. There is moderate bilateral 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.
1. Postsurgical changes of cervical laminoplasty. Cervical canal appears decompressed. Multilevel neural foraminal stenosis is seen at multiple levels related to uncovertebral hypertrophy as detailed above.2. T2 hyperintensity in the cervical cord is seen at the C4-C5 level likely representing myelomalacia and presumably from prior compressive myelopathy.
