New onset ataxia, difficulty with ambulation Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate height. Alignment is maintained. Multilevel disc osteophyte complexes are seen. There is loss of intervertebral disc height, particularly at C5-C6 and C6-C7. There is effacement of the ventral and dorsal thecal sac at the C3-C4 and C4-C5 levels. Bone marrow signal is benign. The cervical spinal cord has normal signal characteristics and overall morphology. There is mild congenital narrowing of the cervical spinal canal with superimposed degenerative changes, with individual levels as below:C2-3: Small disc osteophyte complex. Mild left facet arthropathy with mild left foraminal narrowing. No significant compromise to the spinal canal or right neural foramen. C3-4: Disc osteophyte complex, uncovertebral hypertrophy, and ligamentum flavum thickening resulting in mild to moderate spinal canal stenosis as well as moderate left and mild right neural foraminal narrowing. C4-5: Disc osteophyte complex, uncovertebral hypertrophy, and ligamentum flavum thickening resulting in mild to moderate spinal canal stenosis as well as moderate left and mild right neural foraminal narrowing. C5-6: Small disc osteophyte complex and uncovertebral hypertrophy resulting in mild spinal canal stenosis as well as moderate right and mild left neural foraminal narrowing. C6-7: Disc osteophyte complex and uncovertebral hypertrophy resulting in mild spinal canal stenosis as well as mild to moderate bilateral neural neural foraminal narrowing. C7-T1: Small disc osteophyte complex and uncovertebral hypertrophy. There is no significant spinal canal stenosis. There is mild right foraminal narrowing. The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits. Extensive encephalomalacia involving the right greater than left parieto-occipital lobes is partially visualized.
Multilevel degenerative changes in the cervical spine as detailed above, relatively worse at C3-C4 and C4-C5 levels, where there is mild to moderate spinal canal stenosis. No cord signal abnormality or evidence of frank cord compression at any level.
