Female, 65 years old, with right L5 radiculopathy. The L5 vertebral body demonstrates a transitional lumbosacral morphology. Vertebral body heights are preserved. Spinal alignment is anatomic.Marrow signal characteristics are heterogeneous, likely representing a combination of scattered hemangiomas and degenerative change. In particular, there is evidence of progressive marrow edema centered at L4-5. Small developing Schmorl's nodes are evident along the superior and inferior endplates of L3. No destructive or aggressive osseous lesions are seen.The visualized distal spinal cord, conus and nerve roots of cauda equina are within normal limits. No epidural abnormalities are seen.L1-2: Unremarkable. L2-3: Facet arthropathy and ligamentum flavum thickening, unchanged. Progressive loss of disc height and T2 signal. Mild progressed disc bulging. Mild generalized spinal canal narrowing. Mild bilateral foraminal narrowing. L3-4: Facet arthropathy and ligamentum flavum thickening, unchanged. Disc bulging, mildly progressed. Moderate generalized spinal canal stenosis with effacement of the left lateral recess and crowding of the cauda equina, progressed. Moderate left and mild right foraminal narrowing, progressed. L4-5: Facet arthropathy and ligamentum flavum thickening, unchanged. Progressive loss of disc height and disc bulging. Mild generalized spinal canal stenosis, progressed. Mild bilateral foraminal narrowing. L5-S1: Facet arthropathy and ligamentum flavum thickening, unchanged. No significant spinal canal or foraminal stenosis.
Multilevel degenerative findings are seen with mild progression at several levels. In particular, the spinal canal is now moderately narrowed at the L3-4 level where it was previously only mildly narrowed.
