Female, 71 years old, with cervical myelopathy, left forearm is small, abnormal EMGs, abnormal cervical spine plain films. Slight retrolisthesis of C6 relative to C7 is seen. Sagittal alignment is unremarkable. Mild degenerative loss of vertebral body height is seen at C5 and C6. Vertebral body morphology is otherwise unremarkable. No pathologic marrow replacement is identified.The visualized spinal cord demonstrate normal signal intensity throughout. No epidural abnormalities are suspected.C2-3: No spinal canal stenosis or neuroforaminal narrowing. C3-4: Disc osteophyte formation with a central superiorly directed disc extrusion. Mild impingement of the ventral cord without cord signal abnormality. Mild right foraminal narrowing. C4-5: Minimal posterior disc-osteophyte complex formation. No significant spinal canal or foraminal stenosis. C5-6: Posterior disc-osteophyte complex formation resulting in effacement of the ventral thecal sac but no significant cord impingement or generalized spinal canal stenosis. Severe bilateral foraminal narrowing. C6-7: Posterior disc-osteophyte complex formation. No significant spinal canal stenosis. Severe left and moderate right foraminal narrowing. C7-T1: No spinal canal stenosis or neuroforaminal narrowing. The right mastoid air cells are opacified. The partially visualized thyroid gland appears to be enlarged.
1.Disc osteophyte formation and a central disc extrusion at C3-4 results in mild spinal cord impingement.2.Disc osteophyte formation at C5-6 and C6-7 causes effacement of the ventral thecal sac and significant bilateral foraminal stenosis.
