Clinical question: 1 year post op intradural schwannoma sitting on S1 nerve root. Assess for recurrence. Signs and symptoms: One year follow-up. Pre and post enhanced lumbar MRI1:Examination demonstrates interval improvement of postoperative changes of right laminectomy at L4 level. There is no detectable residual or recurrence of schwannoma. This is a similar observation as prior exam.There is normal anatomical alignment of the vertebral column. Moderate degenerative disc disease at L5-S1 level and mild disc desiccation at L4-L5 is present. There is no evidence of central spinal stenosis at any level.There is no evidence of neural foraminal compromise at any level.There is interval improvement of a midline annular fissure at L4-L5 and with expected residual enhancement. Incidental note is made of small foci of T2 hypointensity in the uterus consistent with a fibroid.
