Left leg weakness, increased severity. Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. There is partial ankylosis involving the C6 and C7 vertebral bodies likely representing a developmental segmentation anomaly. There is mild reversal of cervical lordosis with apex at the C4-C5 level where there is a prominent disc osteophyte complex. Bone marrow signal is benign with marrow signal changes at the C4-C5 levels on a degenerative basis.There is flattening of the cord at the C4-C5 level as described below. Cervical cord is otherwise normal in signal characteristics and 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: No significant compromise to the spinal canal or neural foramina.C4-5: There is a prominent disc osteophyte complex with moderate to severe spinal canal stenosis. There is mild flattening of the cervical cord, particularly on the left. No definite cord signal abnormality. There is mild to moderate left and mild right neural foraminal stenosis. C5-6: No significant compromise to the spinal canal or right neural foramen. Mild left neural foraminal narrowing related to uncovertebral hypertrophy and facet arthropathy.C6-7: No significant compromise to the spinal canal or neural foramina.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. Degenerative changes at C4-C5 level with moderate to severe spinal canal stenosis at this level. There is mild flattening of the cord, particularly on the left, without definite cord signal abnormality.2. Partial fusion involving the C6 and C7 vertebral bodies which likely represents a developmental segmentation anomaly.3. Additional details as above.
