 There is grade 1 anterolisthesis of L4 on L5 measuring up to 6 mm. The vertebral body heights are well-maintained. There is loss of disc height most pronounced at L1/2, L2/3, L4/5 and L5/S1. There is increased T2 signal at the endplates at multiple levels consistent with degenerative changes. The distal spinal cord and conus are within normal limits with the conus terminating at the L1 level. At T12/L1, there is no significant spinal canal or neural foraminal stenosis. At L1-L2, there is a disc bulge with a protrusion eccentric to the right with moderate right neural foraminal and left lateral recess stenosis, but no left neural foraminal stenosis. At L2-L3, there is a a disc bulge with facet hypertrophy and ligamentum flavum thickening without significant spinal canal or neural foraminal stenosis. At L3-L4, there is facet hypertrophy and ligamentum flavum thickening without significant spinal canal or neural foraminal stenosis. At L4-L5, there is degenerative anterolisthesis with facet hypertrophy and ligamentum flavum thickening causing severe spinal canal stenosis with compression and buckling of the nerve roots and moderate right and severe left neural foraminal stenosis. At L5-S1, there is facet hypertrophy and ligamentum flavum thickening without significant spinal canal or neural foraminal stenosis.
Multilevel degenerative spondylosis that is most pronounced at L4-5 with severe spinal canal stenosis, moderate right and severe left neural foraminal stenosis, and grade 1 anterolisthesis.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
