Female, 55 years old, with right greater than left leg pain, history of microdiscectomy. Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. Fatty endplate signal change is seen superiorly at T12. No pathologic marrow replacement, edema or enhancement is observed. The visualized spinal cord, conus and nerve roots of the cauda equina are unremarkable. No pathologic intrathecal enhancement is seen.L1-2: No significant spinal canal stenosis or neuroforaminal narrowing. L2-3: Facet hypertrophy and ligamentum flavum thickening. No significant spinal canal or neuroforaminal stenosis. No interval changes. L3-4: Facet hypertrophy and ligamentum flavum thickening. No significant spinal canal or neuroforaminal stenosis. No interval changes. L4-5: Facet hypertrophy and ligamentum flavum thickening. Minimal bulging disc. Minimal spinal canal narrowing. No significant foraminal compromise. No interval changes. L5-S1: Evidence of prior laminotomy on the right is seen. A previously demonstrated right paracentral disc extrusion has essentially resolved. There remains only slight right paracentral disc focality superimposed on a diffusely bulging disc. Mild narrowing of the right lateral recess is improved from prior. No significant generalized spinal canal stenosis. Mild bilateral foraminal narrowing without interval change.
Findings are seen compatible with the stated history of surgery on the right at L5-S1. A right paracentral disc extrusion seen previously at this level has essentially resolved. Effacement of the right lateral recess has improved. No significant generalized spinal canal stenosis is detected. The foramina are only mildly narrowed at this level. Mild degenerative changes are seen elsewhere in the lumbar spine without significant compromise of the spinal canal or neural foramina.
