Female, 56 years old, falls, left sided weakness. Evaluate for lumbar radiculopathy. For the purposes of numbering, the inferiormost well formed disc is designated L5-S1. There is transitional anatomy at the right L5-S1 level. The vertebral column alignment is within normal limits. The vertebral body heights are preserved. There is disc desiccation at L2-L3, L3-L4 and L4-L5. There is mild loss of disc height at L3-L4, L4-L5 and moderate loss of disc height at L5-S1. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The spinal cord displays normal signal and morphology. There is minimal nonspecific enhancement of the left L3-L4 interspinous soft tissue.T12-L1: Mild bilateral facet degeneration. No significant disc bulge, spinal canal or foraminal stenosis. L1-L2: Mild bilateral facet degeneration. No significant disc bulge, spinal canal or foraminal stenosis. L2-L3: Disc bulge, thickening of the ligamentum flavum and bilateral facet degeneration. No significant spinal canal or foraminal stenosis. L3-L4: Disc bulge, thickening of the ligamentum flavum and bilateral facet degeneration, contributing to mild left L3-L4 foraminal stenosis. No significant spinal canal or right foraminal stenosis. L4-L5: Disc bulge, thickening of the ligamentum flavum and progression of bilateral facet degeneration, contributing to minimal left L4-L5 foraminal stenosis. No significant spinal canal or right foraminal stenosis. L5-S1: Bilateral facet degeneration. No significant disc bulge, spinal canal or foraminal stenosis.
1. Mild degenerative changes of the lumbar spine, without significant spinal canal stenosis. Minimal to mild left foraminal stenosis at L3-L4 and L4-L5.2. Minimal nonspecific enhancement of the left L3-L4 interspinous soft tissue, which may be vascular in etiology versus represent mild interspinous bursitis.3. Transitional anatomy at the right L5-S1 level.
