History of cervical schwannoma, status post resection. Evaluate for recurrence. Surveillance imaging. Again seen are postsurgical changes of C1 and partial C2 for resection of right C2 nerve schwannoma. Again seen is an area of enhancement measuring approximately 9 x 7 mm at the level of the right C2 nerve root in the neural foramen and unchanged. The cervical vertebral bodies are appropriate in overall alignment and height. No abnormal signal in the cervical cord.No significant change in multilevel degenerative changes including mild to moderate spinal canal stenosis at the C6-C7 level related to left paracentral disc extrusion and ligamentum flavum thickening. There is mild flattening of the left ventral cord at this level without cord signal abnormality. Mild degree of spinal canal stenosis is also evident at C3-C4, C4-C5, and C5-C6 and also similar to prior. No abnormal cord signal. Neural foramina are not well evaluated but there is up to moderate neural foraminal stenoses at the right C4-C5 level, right worse than left C5-C6 level, and left worse than right C6-C7 level.
1.Postsurgical changes related to schwannoma involving the right C2 nerve root. There is no significant change in small focus of enhancement at the level of the right C2 nerve root in the neural foramen which may represent minimal residual tumor versus postsurgical change. No evidence of interval enlargement. No abnormal enhancement within the spinal canal to suggest intradural extension.2.No significant change in multilevel degenerative changes in the cervical spine with up to mild to moderate spinal canal stenosis at the C6-C7 level without cord signal abnormality. There is also moderate degree of neural foraminal stenoses at the right C4-C5 level, right worse than left C5-C6 level, and left worse than right C6-C7 level.
