Altered gait, hand numbness Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate height. There is minimal retrolisthesis of C4 on C5 and grade 1 anterolisthesis of C6 on C7. Degenerative changes are seen throughout the cervical spine with evidence of mild progression compared to 4/27/2011. There is severe loss of disc height at C6-C7 and to a lesser degree at C5-C6. Bone marrow signal is benign. No abnormal signal seen within the cervical cord.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: There is a disc osteophyte complex and ligamentum flavum thickening resulting in moderate spinal canal stenosis with effacement of the ventral and dorsal thecal sacs and flattening of the cord contour. No cord signal abnormality. There is uncovertebral hypertrophy and facet arthropathy with mild to moderate bilateral neural foraminal narrowing.C4-5: Minimal disc osteophyte complex, ligamentum flavum thickening, and uncovertebral hypertrophy with mild spinal canal narrowing at this level and mild bilateral neural foraminal narrowing. Mild facet arthropathy.C5-6: Small disc osteophyte complex and effacement of the ventral thecal sac. No significant spinal canal stenosis at this level. There is mild right and moderate left neural foraminal narrowing. There is bilateral facet arthropathy.C6-7: There is disc osteophyte complex at this level with ligamentum flavum thickening and mild to moderate spinal canal stenosis at this level. There is also mild right and mild to moderate left neural foraminal narrowing. There is bilateral facet arthropathy.C7-T1: No significant compromise to the spinal canal or neural foramina. There is bilateral facet arthropathy.The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.
1. Degenerative changes in the cervical spine which have mildly progressed compared to 4/27/2011. There is moderate spinal canal stenosis at C3-C4 with deformity of the cord contour. No cord signal abnormality is appreciated. Lesser degree of spinal canal stenosis is seen at C4-C5 and C6-C7.2. Multilevel neural foraminal narrowing, relatively worse at the C5-C6 and C6-C7 levels on the left.
