 Examination is mildly motion degraded; axial oblique sequence was not obtained. There is grade 1 anterolisthesis of L4 on L5. Otherwise, alignment is within normal limits. There is degenerative disk disease affecting L3-4 and L4-5 with some loss of height. Vertebral body heights and disk spaces are otherwise within normal limits. The distal cord and nerve roots are unremarkable in morphology and signal. The paraspinal soft tissues are unremarkable. Additional level specific findings are as follows:T12-L1: No significant degenerative disk disease, central canal, or neural foraminal stenosis.L1-L2: No significant degenerative disk disease, central canal, or neural foraminal stenosis.L2-L3: No significant degenerative disk disease, central canal, or neural foraminal stenosis.L3-L4: Degenerative disk disease with mild disk bulge and facet degenerative changes without significant central stenosis. Mild to moderate left neuroforaminal stenosis.L4-L5: Degenerative disk disease, ligamentum flavum thickening, and facet degenerative changes results in mild central canal stenosis. Disk protrusion into the left lateral recess results in moderate-severe left neural foraminal stenosis. There is mild-moderate right neuroforaminal stenosis.L5-S1: Degenerative disk disease with mild disk bulge and facet degenerative changes without significant central stenosis. Mild left neuroforaminal stenosis.
Degenerative lumbar spondylosis most severely affecting L4-L5 as described above with grade 1 anterolisthesis. There is mild spinal canal stenosis, moderate-severe left neuroforaminal, and mild to moderate right neuroforaminal stenosis at L4-5. There is also mild to moderate left L3-4 neural foraminal stenosis.
