Sciatica, rule out progression of DJD Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is grade 1 anterolisthesis of L4 on L5 similar to prior. Alignment is otherwise within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.Small disc bulges at T11-T12 and T12-L1 again partially imaged. Multilevel degenerative changes are seen in the lumbar spine, as described below, which are not significantly changed since prior lumbar spine MRI from 7/9/2014.L1-L2: Disc desiccation with mild ligamentum flavum thickening and mild facet arthropathy. No spinal canal or neural foraminal stenosis.L2-L3: Disc desiccation with mild ligamentum flavum thickening and mild facet arthropathy. No spinal canal or neural foraminal stenosis.L3-L4: Disc desiccation with mild ligamentum flavum thickening and mild facet arthropathy. No spinal canal or neural foraminal stenosis.L4-L5: There is grade 1 anterolisthesis, advanced bilateral facet arthropathy, and ligamentum flavum thickening with resulting moderate spinal canal stenosis at this level similar to prior. There is mild bilateral neural foraminal stenosis, similar to prior.L5-S1: Severe disc height loss as before. There is mild disc bulge eccentric to the right and moderate bilateral facet arthropathy. There is no central spinal canal stenosis. There is however effacement of the right lateral recess similar to prior. There is also severe bilateral, right worse than left neural foraminal stenosis, also similar to prior. There may be impingement of the bilateral exiting L5 and possibly descending right S1 nerve roots at this level.
1. Degenerative changes in the lumbar spine, particularly at the L4-L5 and L5-S1 levels, are not significantly changed since 7/9/2014. 2. Grade 1 anterolisthesis, advanced facet arthropathy, and moderate spinal canal stenosis at L4-L5 similar to prior. Instability at this level is demonstrated on prior flexion-extension radiographs.3. Again seen at L5-S1 is severe bilateral, right worse than left, neural foraminal stenosis. There is also effacement of the right lateral recess at this level as before. 4. Additional levels as above.
