 For the purposes of numbering there are 5 lumbar type vertebral bodies. Vertebral body heights are maintained. The marrow signal is benign. The conus is normal in signal and morphology and terminates at an appropriate level. There is grade 1 anterolisthesis of L5 on S1, grade 1 retrolisthesis of L3 on L4, grade 1 retrolisthesis of L2 on L3, and minimal retrolisthesis of L1 on L2. The visualized intra-abdominal and paraspinal contents are unremarkable.Degenerative changes are seen, with individual levels as below:T12/L1: There is no spinal canal or neural foraminal narrowing.L1/2: There is a mild disc bulge. No significant spinal canal narrowing. There is mild bilateral neural foraminal narrowing.L2/3: There is disc bulge with minimal spinal canal narrowing and mild bilateral neuroforaminal narrowing, right greater than left. There is mild facet hypertrophy.L3/4: There is a disc bulge with mild spinal canal narrowing. There is mild bilateral neuroforaminal narrowing, right greater than left. There is facet hypertrophy.L4/5: There is a disc bulge and bilateral facet arthropathy. No significant spinal canal narrowing. There is severe right and moderate to severe left neural foraminal narrowing.L5/S1: There is bilateral L5 spondylolysis with grade 1 anterolisthesis of L5 on S1. Advanced bilateral facet arthropathy. No spinal canal narrowing. Moderate to severe bilateral neural foraminal stenosis.
1. Multilevel degenerative changes. No high grade spinal canal stenosis.2. There is bilateral L5 spondylolysis with grade 1 L5-S1 spondylolisthesis. Additional levels of spondylolisthesis as above.3. Moderate to severe neural foraminal stenosis at L4-5 and L5-S1 bilaterally as detailed above. 4. Advanced facet arthropathy in the lower lumbar spine.
