81-year-old male with pain and tingling left leg. Evaluate for lumbar radiculopathy. Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall alignment and height. The conus medullaris on sagittal imaging is grossly intact.At L5-S1 there is disk desiccation, moderate disk bulge, ligament flavum hypertrophy and facet arthropathy causing mild narrowing of the spinal canal at this level. There is moderate right and mild left neural foraminal stenosis. At L4-5 there is disk dessication, diffuse disk bulge, ligamentum flavum hypertrophy and asymmetric facet osteoarthritic changes, right greater than left, with associated mild to moderate right neural foraminal narrowing. There is no significant compromise to the spinal canal or right neural foramen. At L3-4 there is disk dessication, mild diffuse disk bulge, ligamentum flavum hypertrophy and facet arthropathy. There is no significant narrowing of the spinal canal or neural foramina.At L2-3 there is disk dessication, minimal disc bulge with no significant compromise to spinal canal or neural foramina.At L1-2 there is no significant compromise to spinal canal or neural foramina.
Multilevel degenerative disk disease predominantly affecting the lower spine as described above related to disk bulge, ligamentum flavum hypertrophy and facet osteoarthritic changes.
