77-year-old male with history of lumbosacral pain. There is mild straightening of the lumbar spine in the sagittal plane. The distal spinal cord and conus are within normal limits with the conus terminating at the L1 level. There is mild sacral canal epidural lipomatosis. There is diffuse paraspinal muscle atrophy. There are bilateral probable renal cysts, although incompletely characterized. The vertebral body heights are well-maintained. However, there is disc space loss and vacuum disc phenomenon at multiple levels. There are multilevel degenerative endplate changes with a few Schmorl nodes, with additional degenerative changes as follows:T12-L1: There is a disc bulge, but no significant spinal canal stenosis or neural foramen narrowing.L1-2: There is a disc bulge and facet hypertrophy resulting in mild spinal canal stenosis and mild bilateral neural foramen narrowing. There is a small amount of fluid within the left facet joint.L2-3: There is a disc bulge, ligamentum flavum thickening, and facet hypertrophy resulting in moderate spinal canal stenosis and mild bilateral neural foramen narrowing. There is a small amount of fluid within the right facet joint.L3-4: There is a disc bulge, ligamentum flavum thickening, and facet hypertrophy resulting in severe spinal canal stenosis and mild to moderate bilateral neural foramen narrowing. There is fluid within bilateral facet joints.L4-5: There is a disc bulge, ligamentum flavum thickening, and facet hypertrophy resulting severe spinal canal stenosis and mild to moderate bilateral neural foramen narrowing. L5-S1: There is a disc bulge ligamentum flavum thickening, and facet hypertrophy with mild spinal canal stenosis. There is moderate bilateral neural foramen narrowing.
Extensive multilevel degenerative spondylosis of the lumbar spine, which is most pronounced at L3-4 and L4-5, where there is severe spinal canal stenosis.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
