Female, 44 years old, with neck pain, history of fusion at C4-5. Evidence of anterior instrumented fusion is seen at C5-6. The cervical lordosis is straightened. Otherwise, sagittal alignment is within normal limits. Vertebral body height and morphology are unremarkable. No evidence of marrow replacement or marrow edema is seen. The left aspect of the spinal cord appears slightly reduced in volume relative to the right at the C5-6 level. In addition, there is a small area of ill-defined T2 signal abnormality within the left cord at this level. Elsewhere, the spinal cord demonstrates normal signal intensity and morphology. No epidural abnormalities are suspected.Mild edema is demonstrated along the supraspinous ligament and soft tissues surrounding the C7 spinous process.C2-3: Mild facet arthropathy. No significant spinal canal or foraminal stenosis. C3-4: Mild facet arthropathy. No significant spinal canal or foraminal stenosis. C4-5: Facet arthropathy, left more than right. Posterior disc-osteophyte complex formation with a superimposed superiorly directed central extrusion and right paracentral protrusion. Effacement of the thecal sac with mild flattening of the ventral cord. No significant foraminal narrowing. C5-6: Mild facet arthropathy. Obliteration of the intervertebral disc. No significant spinal canal or foraminal stenosis.C6-7: Facet arthropathy. Minimal posterior disc-osteophyte complex formation. No significant spinal canal or foraminal stenosis. C7-T1: No spinal canal stenosis or neuroforaminal narrowing.
1.Evidence of prior anterior instrumented fusion is seen at the C5-6 level. Mild degree of left spinal cord myelomalacia and may represent the effect of a prior stenosis at this level. However, on the present examination, no significant spinal canal or foraminal stenosis is seen at this level.2.Relatively mild disc and facet degeneration are seen at additional levels as above. Most notably, a disc extrusion and protrusion are evident at the C4-5 level with resultant effacement of the ventral thecal sac. There are no additional areas of significant spinal canal or foraminal stenosis.3.Mild edema is seen along the supraspinous ligament and the soft tissue surrounding the C7 spinous process. Correlation with point tenderness is suggested. This could represent a mild strain injury or a mild traumatic injury.
