Neurogenic claudication and lumbar stenosis/spondylolisthesis. There is 5 mm of anterolisthesis of L3 on L4 and minimal anterolisthesis of L5 on S1. The vertebral body heights are preserved. There is multilevel disc narrowing with signal desiccation, which is most prominent at L3-4, L4-5, and L5-S1. The vertebral bone marrow signal is unremarkable aside from degenerative endplate signal alterations. The conus terminates at the inferior L1 level. There is diffuse atrophy of the lower paraspinal muscles. At T9 though T12, posterior disc-osteophyte complexes result in indentation of the spinal cord, as well as bilateral neural foraminal stenosis. At L2-L3, there is minimal disc bulging and mild bilateral facet arthropathy and ligament flavum hypertrophy with mild right and moderate left neural foraminal stenosis, but no significant central stenosis. At L3-L4, there is moderate bilateral facet arthropathy, and ligamentum flavum hypertrophy causing severe central stenosis in conjunction with the anterolisthesis. There is also mild right and moderate left neural foraminal stenosis at this level. At L4-5, a central disc protrusion superimposed on disc bulging, as well as moderate bilateral facet arthropathy result in moderate to severe spinal canal stenosis and mild-to-moderate right and moderate left foraminal stenosis. At L5-S1, a central disc protrusion superimposed on disc bulging, as well as mild bilateral facet arthropathy result in mild right and severe bilateral neural foraminal stenosis and mild spinal stenosis.
1. Marked multilevel degenerative lumbar spondylosis with grade 1 anterolisthesis and moderate to severe spinal canal stenosis at L3-4 moderate to severe spinal canal stenosis, moderate to severe spinal canal stenosis at L4-5, as well as severe bilateral neural foraminal stenosis at L5-S1.2. Degenerative spondylosis in the imaged portions of the lower thoracic spine with indentation of the spinal cord by disc-osteophyte complexes.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
