Bilateral wrist drop. Evaluate for cervical lesion. Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. Bone marrow signal is benign. No cord signal abnormality. There is loss of normal cervical lordosis with associated altered contour of the cervical cord. There is mild anterolisthesis of C4 on C5 and mild retrolisthesis C6 on C7. Multilevel degenerative changes are present including severe disc height loss at the C4-C5 level and to a lesser degree C5-6 and C6-C7 levels. Additional details as below:C2-3: No significant compromise to the spinal canal. There is bilateral facet arthropathy with mild narrowing of the left neural foramen. No significant right neural foraminal narrowing.C3-4: Mild disc bulge and ligamentum flavum thickening contribute to mild spinal canal narrowing. There is mild right and moderate to severe left neural foraminal stenosis. Prominent left-sided facet arthropathy.C4-5: There is effacement of the ventral thecal sac without significant stenosis of the spinal canal overall. There is mild right and moderate left neural foraminal stenosis.C5-6: There is moderate spinal canal stenosis related to disc osteophyte complex, ligamentum flavum thickening, and kyphotic deformity of the cervical spine at this level. There is severe right and mild left neural foraminal stenosis.C6-7: No significant compromise to the spinal canal. There is mild narrowing of the neural foramina.C7-T1: No significant compromise to the spinal canal or neural foramina. Bilateral facet arthropathy.The vertebral artery flow voids appear to be intact. There is artifact involving the left lateral C4 and C5 levels favored to be related to tortuosity of the left vertebral artery. Paraspinous soft tissue structures appear within normal limits.
1. Moderate degenerative changes throughout the cervical spine. There is up to moderate spinal canal stenosis at the C5-C6 level. There is multilevel neural foraminal stenoses, particularly at the left C3-C4 and C4-C5 levels as well as the right C5-C6 level.2. No abnormal cord signal or masses involving the spinal canal.
