Anterolisthesis, radiculopathy symptoms in the lower extremities Examination is moderately motion degraded. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is grade 1 anterolisthesis at L4-L5 on the current images which is worse on the upright recent radiographs indicative of instability. Bone marrow signal is benign. The conus medullaris is normal in position.Multilevel degenerative changes are seen, as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: Mild disc bulge which is eccentric to the left. Minimal left neural foraminal narrowing. No spinal canal or right neural foraminal stenosis.L3-L4: Mild disc bulge with suggestion of a small right foraminal annular fissure and small protrusion. There is also ligamentum flavum thickening, prominence of the dorsal epidural fat and fairly mild facet arthropathy contributing to mild spinal canal stenosis. There is mild to moderate right and minimal left neural foraminal stenosis.L4-L5: Grade 1 anterolisthesis as described above with disc uncovering,, disc bulge ligamentum flavum thickening, and advanced bilateral facet arthropathy with facet joint distention. These findings contribute to moderate degree of spinal canal stenosis. There is mild disc height loss. There is also mild to moderate right and moderate left neural foraminal stenosis.L5-S1: Disc desiccation with mild bulge. There is a right posterior paracentral annular fissure. Bilateral facet arthropathy. There is tapering of the thecal sac with prominence of the dorsal epidural fat. No high-grade spinal canal stenosis. Neural foramina are also patent.Small multilevel disc bulges in the lower thoracic spine are partially imaged. Paraspinous soft tissues are within normal limits.
1. Multilevel degenerative changes in the lumbar spine worst at the L4-L5 level where there is grade 1 anterolisthesis on a degenerative basis with advanced facet arthropathy. Recent upright radiographs demonstrate greater degree of anterolisthesis indicating instability. There is moderate spinal canal stenosis at this level as well as moderate left and mild to moderate right neural foraminal stenosis.2. Mild spinal canal stenosis as well as mild to moderate right neural foraminal stenosis at L3-L4. Additional levels as above.3. Motion degraded examination.
