Female, 55 years old, with left lumbar radiculopathy. Trace anterolisthesis of L4 relative to L5 is seen. Otherwise, spinal alignment is anatomic. Vertebral body height and morphology are within normal limits allowing for degenerative endplate changes at L5-S1. No suspicious marrow replacement is seen. The visualized distal spinal cord, conus and nerve roots of the cauda equina are unremarkable. No epidural abnormalities are suspected.L1-2: Minimal facet arthropathy. No spinal canal or foraminal stenosis. L2-3: Unremarkable. L3-4: Minimal facet arthropathy. No spinal canal or foraminal stenosis. L4-5: Advanced facet arthropathy with a facet effusion on the left. Ligamentum flavum thickening. Minimal disc bulging. Findings contribute to produce a mild spinal canal stenosis. Moderate to severe narrowing of the left neural foramen. Moderate narrowing of the right neural foramen. L5-S1: Facet arthropathy. Ligamentum flavum thickening. Disc bulging with a superimposed shallow left paracentral protrusion. No significant spinal canal stenosis. Moderate left and mild right foraminal narrowing.
Moderate degenerative findings are seen in the lower lumbar spine. Most notably at L5-S1, the combination of advanced facet arthropathy, ligamentum flavum thickening and disc bulging causes mild spinal canal stenosis, moderate to severe left and moderate right foraminal narrowing.
