Male, 62 years old, with imbalance. Assess for myelopathy. Since the prior examination, anterior instrumented fusion has been performed from C3 through C5. The cervical lordosis is slightly exaggerated at C2-3, and straightened from C3 and below, though this could be at least in part due to positioning.Vertebral body heights are preserved. No evidence of any marrow signal abnormality or marrow edema is seen where the presence of orthopedic instruments do not interfere with the assessment.The visualized spinal cord demonstrates normal morphology and signal characteristics except as discussed below.C2-3: Mild facet hypertrophy. No significant spinal canal or foraminal stenosis. Improved from the prior examination where there was evidence of disc osteophyte disease and cord impingement. C3-4: Mild facet hypertrophy. Very mild persistent disc osteophyte complex formation, but significantly improved from the prior examination. There is no longer any evidence of cord impingement. A small focus of T2 hyperintensity within the right lateral aspect of the cord probably reflects chronic myelomalacia from cord impingement which was previously seen at this level. Mild to moderate bilateral foraminal narrowing, similar to prior. C4-5: Mild facet hypertrophy. Mild persistent disc osteophyte complex formation. Mild effacement of the ventral thecal sac with mild flattening of the ventral cord but no cord signal abnormality, stable or improved relative to prior. Mild to moderate bilateral foraminal narrowing, similar to prior. C5-6: Facet hypertrophy. Minimal posterior disc-osteophyte complex formation but with substantial bilateral uncovertebral hypertrophy. No significant generalized spinal canal stenosis. Severe bilateral foraminal narrowing. No significant interval changes. C6-7: Facet hypertrophy. Mild posterior disc-osteophyte complex formation with bilateral uncovertebral hypertrophy. No significant generalized spinal canal stenosis. Severe bilateral foraminal narrowing. No significant interval changes.C7-T1: Facet hypertrophy. No significant spinal canal or foraminal stenosis. No significant interval changes.
1.Since the prior examination, anterior instrumented fusion has been performed spanning from C3 through C5. Significant disc osteophyte disease seen on the prior examination with cord impingement at these levels has significantly improved. No high-grade spinal canal stenosis is seen, though there remain small disc osteophyte complexes at several levels which slightly indent the ventral spinal cord.2.Below the fused levels, no significant interval changes are seen. Severe bilateral foraminal narrowing persists at C5-6 and C6-7, largely due to uncovertebral hypertrophy.
