 For numbering purposes, 5 lumbar type vertebral bodies are identified. Alignment is anatomic. The marrow signal is generally somewhat heterogenous, particularly centered on the L4-5 endplates, suggestive of degenerative changes and similar to prior exam.The conus is normal in signal and morphology and terminates at T12-L1 level. The visualized intra-abdominal and paraspinal contents are unremarkable. T12/L1: No significant spinal canal or neural foraminal stenosis.L1/2: No significant spinal canal or neural foraminal stenosis.L2/3: No significant spinal canal or neural foraminal stenosis.L3/4: There is mild facet joint arthropathy resulting in a mildly narrowed left neural foramen. Otherwise no significant spinal canal or right foraminal stenosis.L4/5: There is loss of intervertebral disc space with diffuse disc bulge, facet joint arthropathy, and ligamentum flavum thickening resulting in moderate spinal canal stenosis and mild bilateral neural foraminal narrowing. Overall, there appears to be minimal improvement in the disc bulge, with less effacement of the lateral recesses. The posterior elements are unchanged.L5/S1:Mild facet joint arthropathy with no significant spinal canal or neural foraminal stenosis.SI Joints: No significant abnormalities noted.
Multilevel degenerative disease of the lumbar spine, most prominent at L4-L5 level with diffuse disc bulge and moderate spinal canal stenosis. Overall, there appears to be improvement in disc bulge at the L4-5 level with decrease in effacement of the thecal sac and left lateral recesses. Otherwise the exam is not significantly changed as compared to prior study from 11/14/2011.
