Male, 74 years old, with progressive gait deterioration. Grade 1 anterolisthesis of C4 relative to C5 is seen, progressed from the prior examination. A mild reversal of the normal cervical lordosis has developed as well.Progressive disc degeneration is seen between C4 and C7 with further loss of disc height and endplate integrity and degenerative loss of vertebral body height. No significant marrow edema is detected. Ventral epidural thickening from C4 through C7 has also progressed, likely secondary to degeneration of the adjacent discs.Sequelae of prior laminectomy are again seen from C3-C7. The spinal canal remains decompressed in this region similar to prior. The spinal cord is thinned in the area of laminectomy and there is superimposed focal signal abnormality at the C5 level compatible with myelomalacia. Elsewhere, the cord is unremarkable.C2-3: Right facet arthropathy. Minimal posterior disc-osteophyte complex formation. No significant spinal canal stenosis. Mild right foraminal narrowing. No interval changes. C3-4: Facet arthropathy. Mild posterior disc-osteophyte complex formation. No significant spinal canal stenosis. Moderate to severe bilateral foraminal narrowing. No interval changes. C4-5: Bilateral facet arthropathy. Posterior disc-osteophyte complex formation asymmetric to the right paracentral and foraminal zones. No spinal canal stenosis. Severe bilateral foraminal narrowing. No interval changes. C5-6: Facet arthropathy. Progressive disc and endplate degeneration with disc osteophyte formation. No significant spinal canal stenosis. Severe bilateral foraminal narrowing, likely progressed. C6-7: Facet arthropathy. Progressive disc and endplate degeneration with disc osteophyte formation. No significant spinal canal stenosis. Severe left foraminal narrowing, unchanged. C7-T1: Progressive disc and endplate degeneration with disc osteophyte formation. Moderate generalized spinal canal narrowing which has slightly progressed. Severe bilateral foraminal narrowing, similar to prior.
1.Multilevel disc degeneration has progressed between C4 and C7. Although most of these levels have been surgically decompressed, a moderate canal narrowing is evident at C7-T1.2.The spinal cord remains thinned between C4 and C7 with focal chronic myelomalacia at the C5 level. No other cord abnormalities are identified.3.Evidence of prior laminectomy for spinal canal decompression is seen between C3 and C7.
