Female, 64 years old, with cervicalgia and spinal stenosis, history of cervical fusion. Preoperative evaluation for corpectomy. Again demonstrated is partial osseous fusion of the C6 and C7 vertebrae. Spinal alignment is anatomic. Vertebral body heights are preserved allowing for endplate degeneration. No evidence of marrow edema or pathologic marrow replacement is seen.The visualized spinal cord shows normal signal throughout. No epidural lesions are suspected.C2-3: Bilateral facet arthropathy. No spinal canal stenosis. Mild right foraminal narrowing. No interval changes. C3-4: Advanced facet arthropathy on the left. No spinal canal stenosis. Moderate left foraminal narrowing. No interval changes. C4-5: Bilateral facet arthropathy. Posterior disc-osteophyte complex formation. Mild effacement of the ventral thecal sac. Mild right foraminal narrowing. No interval changes. C5-6: Broad posterior disc-osteophyte complex formation causing at least moderate spinal canal stenosis with some deformation of the spinal cord but no evidence of cord edema. Moderate left and mild right foraminal narrowing. No interval changes. C6-7: No significant spinal canal or foraminal stenosis. C7-T1: No significant spinal canal or foraminal stenosis.
1.Fusion of the C6 and C7 vertebrae is redemonstrated compatible with prior surgery.2.A broad disc osteophyte at C5-6 continues to produce moderate spinal canal stenosis and mild deformation of the cord, similar to prior.3.Scattered additional degenerative changes, including mild-to-moderate foraminal narrowing as above, show no significant interval change.
