Female, 47 years old, with radiculopathy. Spinal alignment is anatomic. Vertebral body heights are preserved. Marrow signal characteristics are heterogeneous but there are no areas of suspicious focal marrow replacement. Edema is evident centered on the left L5-S1 facet joint and left L5 pedicle. The visualized distal spinal cord, conus and nerve roots of the cauda equina are within normal limits. No epidural abnormalities are suspected.L1-2: Facet arthropathy. No spinal canal or foraminal stenosis. L2-3: Facet arthropathy. No spinal canal or foraminal stenosis. L3-4: Facet arthropathy and ligamentum flavum thickening. Minimal disc bulging. No spinal canal or foraminal stenosis. L4-5: Facet arthropathy and ligamentum flavum thickening. Minimal disc bulging. No spinal canal or foraminal stenosis. L5-S1: Facet arthropathy, particularly on the left with edema as above. Ligamentum flavum thickening. Minimal disc bulging. No spinal canal stenosis. Mild bilateral foraminal narrowing.
1.Severe degeneration of the left L5-S1 facet joint is seen with associated marrow edema. Nevertheless, this results in only a mild narrowing of the neural foramen.2.Elsewhere, only mild degenerative findings are seen. No significant disc herniation is detected. No spinal canal stenosis is observed.
