Right lower extremity radiculopathy, patient receiving lumbar epidural injections Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is grade 1 anterolisthesis of L2 on L3. There is grade 2 anterolisthesis and mild right lateral subluxation of L3 on L4. There is dextrocurvature with apex at L2-3. Bone marrow signal is benign. The conus medullaris is normal in position.Multilevel degenerative changes are seen, as described below:L1-L2: There is disk bulge, ligamentum flavum thickening, and facet arthropathy. There is loss of intravertebral disk space. There is moderate right and minimal left neural foraminal narrowing. No significant spinal canal narrowing.L2-L3: Anterolisthesis, severe loss of disk height, and disk bulge eccentric to the right. There is bilateral facet arthropathy and ligamentum flavum thickening. There is severe spinal canal stenosis. There is moderate bilateral neural foramina stenosis. L3-L4: Grade 2 anterolisthesis, severe loss of disk height, bilateral facet arthropathy and ligamentum flavum thickening. There is severe spinal canal stenosis and moderate right and moderate to severe left neural foramina stenosis.L4-L5: Disk desiccation with some loss of height. There is bilateral facet arthropathy and ligamentum flavum thickening. No significant spinal canal stenosis. There is minimal right and moderate to severe left neural foraminal stenosis.L5-S1: There is a disk bulge and mild facet arthropathy. No spinal canal stenosis. There is mild right foraminal narrowing. No spinal canal or left neural foraminal stenosis. There is contact of the disk bulge with the bilateral L5 nerve roots extra foraminally.There is atrophy involving the paraspinous musculature.
1. Multilevel degenerative changes in the lumbar spine as detailed above with grade 1 anterolisthesis of L2 on L3 and grade 2 anterolisthesis with mild right lateral subluxation of L3 on L4. There is dextrocurvature with apex at L2-3.2. Severe spinal canal stenosis at L2-L3 and L3-L4. 3. Multilevel neural foraminal narrowing and facet arthropathy as described above.
