 Vertebral body heights in the lumbar spine are normal. Alignment is maintained. The marrow signal is benign. The conus is normal in signal and morphology and terminates at an appropriate level. Axial images are slightly motion degraded. No significant change however is seen in degenerative changes compared to 2/5/2013. Individual levels as below:T12/L1: No significant spinal canal stenosis or neuroforaminal narrowing.L1/2: No significant spinal canal stenosis or neuroforaminal narrowing.L2/3: Minimal broad based disk bulge, facet hypertrophy, and ligamentum flavum hypertrophy. No significant spinal canal stenosis or neuroforaminal narrowing.L3/4: Mild broad based disk bulge, facet hypertrophy and ligamentum flavum hypertrophy without significant spinal canal stenosis. There is minimal bilateral foraminal narrowing. L4/5: Broad based disk bulge, ligamentum flavum hypertrophy and facet hypertrophy without significant spinal canal stenosis. Loss of disk height with disk desiccation and degenerative endplate changes. Mild bilateral neuroforaminal narrowing.L5/S1: Degenerative endplate marrow changes with mild edema. There is significant loss of disk height minimally worse compared to prior. There is a diffuse disk bulge with component of disk extrusion not significantly changed since prior. There is severe bilateral neural foraminal stenosis which may be impinging on the exiting L5 nerve roots. There is also effacement of the lateral recesses and contact of the traversing S1 nerve roots, worse on the right. No significant central canal stenosis. There is bilateral facet arthropathy similar to prior.There is mild volume loss involving the paraspinous and iliopsoas musculature similar to prior. Paraspinous soft tissues are otherwise unremarkable.
Compared to 2/5/2013, minimal worsening of loss of disk height at the L5-S1 level. Otherwise no significant change in advanced degenerative changes at the L5-S1 levels with severe bilateral neural foraminal stenosis and suspected impingement of the exiting L5 nerve roots.Remainder of the levels as detailed above
