Reason: postcontrast MRI due to abnormal noncontrast MRI per radiology recommendation History: as above Examination is limited to post contrast sequences, with precontrast imaging performed recently on 5/21/2016. There is a punctate nodule measuring 2 x 5 mm near the midline along the cauda equina nerve roots at the L1-L2 level which is again seen. Due to its small size, the lesion is not well appreciated on the axial sequences. No suspicious enhancement is appreciated elsewhere in the spine. Degenerative findings including right paracentral disc protrusion contributing to at least moderate spinal canal stenosis at L4-L5 again seen. Enhancement is evident associated with the dorsal annular fissure and disc protrusion at the L4-L5 level. Disc protrusion at the L5-S1 is also again seen. Neural foramina are patent.Please see prior report for additional details.
2 x 5 mm intradural extramedullary lesion at the L1-L2 level is again seen and statistically likely represents an incidental schwannoma. When follow-up is considered, perhaps in 6 months, would suggest obtaining thin slices through this region.Please refer to separate report dated 5/21/2016 for additional findings including spinal canal stenosis at the L4-L5 level.
