 The sagittal images include inferior endplate of T11 vertebral body. Grade I retrolisthesis of L1 on L2. Otherwise the alignment of the lumbar spine is grossly within normal limits. There is very mild wedging of the T12 vertebral body, which may be physiologic. There is no evidence of acute fracture or subluxation. There are multilevel degenerative changes with multilevel disc height loss, worst at the L1-L2 level with fatty endplate changes. Prior images are partially available for comparison, but there appears to be some progression since 2011. The conus terminates at the L1 level and is normal in signal.T12/L1: Mild disc bulge and facet arthropathy without significant spinal canal stenosis. Mild right neural foraminal narrowing. No significant left neural foraminal narrowing.L1/2: Posterior osteophyte and disc bulge with a prominent left lateral recess and foraminal component and facet arthropathy with moderate to severe left neural foraminal narrowing which may be impinging on the exiting left L1 nerve root. There is minimal right neural foraminal narrowing. Mild spinal canal stenosis. L2/3: Right central disc protrusion and facet arthropathy with mild spinal spinal canal stenosis and also moderate right neural foraminal narrowing. No significant left neural foraminal narrowing.L3/4: Broad-based disc bulge, facet arthropathy, and ligamentum flavum thickening with moderate spinal canal stenosis and mild right and mild to moderate left bilateral neural foraminal narrowing.L4/5: Diffuse disc bulge, facet arthropathy, and ligamentum flavum thickening with mild to moderate spinal canal stenosis, moderate right greater than left neural foraminal narrowing.L5/S1:Minimal disc bulge with bilateral moderate neural foraminal narrowing. No significant spinal canal stenosis.
Multilevel degenerative changes throughout the lumbar spine. There is moderate spinal canal stenosis at L3-L4 and mild to moderate at L4-L5. Multilevel neural foraminal stenosis as above.
