 The last well formed disk space is referred to as L5-S1. There is normal alignment of the lumbar spine. There is disk desiccation and loss of disk height at L3-4 and L4-5. The osseous marrow signal is benign. The vertebral body heights are preserved. The conus shows normal signal and caliber and terminates at L1.T11-12: No disk herniation or spinal stenosis.T12-L1: No disk herniation or spinal stenosis.L1-2: No disk herniation or spinal stenosis.L2-3: Minimal disk bulge and bilateral facet arthropathy with no significant spinal stenosis.L3-4: Diffuse disk bulge, facet arthropathy and ligamentum flavum thickening causing mild to moderate bilateral neural foraminal stenosis and no significant spinal canal stenosis. There may be impingement of the exiting L3 nerve roots.L4-5: Diffuse disk bulge with left foraminal protrusion component. There is bilateral facet arthropathy. There is resulting moderate to severe bilateral left worse than right neural foraminal stenosis. No significant spinal canal stenosis. There may be impingement of the exiting L4 nerve roots, particularly on the left.L5-S1: Mild disk bulge and facet arthropathy with no significant spinal canal or neural foraminal stenosis.
Multilevel degenerative changes as detailed above with moderate to severe L4-L5 and moderate L3-L4 neural foraminal stenosis as above. No significant spinal canal stenosis.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
