 For the purposes of numbering, there are 5 lumbar-type vertebral bodies. There is a grade I anterolistheses of L3 on L4 and L4 on L5, similar to the prior exam. Vertebral bodies heights are maintained. Fatty marrow changes are noted in the L4-L5 vertebral bodies. There has been slight interval worsening of degenerative spondylosis, notably at L4-5 where there is now complete loss of disc height. There is ex vacuo phenomenon at the intervertebral disc spaces of L3/4, L4/5, and L5/S1. The conus is normal in signal and morphology and terminates at T12-L1. There is a mild disc bulge at T9/10 with mild spinal canal stenosis as seen on the sagittal images.T10/11: Mild disc bulge and ligamentum flavum thickening with mild spinal canal stenosis, moderate right neural foraminal narrowing, and mild left neural foraminal narrowing.T11/12: Mild disc bulge, facet arthropathy, ligamentum flavum thickening with mild left neural foraminal narrowing. No significant spinal canal stenosis or right neural foraminal narrowing.T12/L1: Worsening broad-based disc bulge, facet arthropathy, and ligamentum flavum thickening with mild to moderate spinal canal stenosis and mild to moderate bilateral neural foraminal narrowing. L1/2: Worsening broad-based disc bulge, facet arthropathy, ligamentum flavum thickening with mild spinal canal stenosis, mild to moderate right neural foraminal narrowing and no left neural foraminal narrowing.L2/3: Worsening broad-based disc bulge, facet arthropathy, ligamentum flavum thickening and mild spinal canal stenosis with minimal bilateral neural foraminal narrowing.L3/4: Worsening broad-based disc bulge, facet and ligamentum flavum thickening with moderate spinal canal stenosis and moderate bilateral neural foraminal narrowing.L4/5: Pseudobulge, facet arthropathy, and ligamentum flavum thickening with moderate spinal canal stenosis, moderate right and moderate to severe left neural foraminal narrowing.L5/S1:Disc bulge without significant spinal stenosis. Moderate right and mild to moderate left neural foraminal narrowing.
1. Advanced degenerative changes of the lumbar spine, slightly worse since prior, with moderate spinal canal stenosis at L3/4 and L4/5. 2. Multilevel neural foraminal narrowing as described above.
