Female, 74 years old, with history of cervical schwannoma status post resection. Yearly evaluation for tumor recurrence. Findings are redemonstrated compatible with laminectomy at C1 and partial laminectomy at C2 on the right. A 9 x 7 mm focus of enhancement in the operative bed along the right C2 nerve root is unchanged. No new enhancing lesions are seen.Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. No pathologic marrow replacement or edema is seen. The visualized spinal cord shows normal signal intensity and morphology.C2-3: No significant spinal canal or foraminal stenosis. C3-4: Posterior disc-osteophyte complex formation. Ligamentum flavum thickening. Mild spinal canal stenosis. Moderate left and mild right foraminal narrowing. No changes. C4-5: Posterior disc-osteophyte complex formation. Ligamentum flavum thickening. Mild spinal canal stenosis and mild bilateral foraminal narrowing. No changes.C5-6: Minimal posterior disc-osteophyte complex formation. Ligamentum flavum thickening. Mild spinal canal stenosis. No significant foraminal narrowing. No changes.C6-7: Posterior disc-osteophyte complex formation with a left paracentral fusion. Ligamentum flavum thickening. Moderate spinal canal stenosis with slight flattening of the left ventral cord. Moderate left and mild right foraminal narrowing. No changes. C7-T1: No spinal canal or foraminal stenosis.
Postoperative findings are redemonstrated compatible with schwannoma resection at the right C1-2 neural foramen. Nonspecific enhancing tissue in the operative bed is unchanged. No new or growing lesions are detected.
