Male, 73 years old, with lumbar radiculopathy, spondylolysis and spondylolisthesis. Grade 1 anterolisthesis of L5 relative to S1 is unchanged. Associated bilateral L5 spondylolysis is also redemonstrated.Elsewhere, spinal alignment is anatomic. Vertebral body height is preserved. Scattered areas of degenerative endplate marrow signal abnormality are seen.The visualized spinal cord, conus and cauda equina are unremarkable except as discussed below.L1-2: Mild left foraminal and far lateral disc bulging which is probably slightly progressed from prior. No significant spinal canal or neuroforaminal stenosis. L2-3: Facet hypertrophy. Progressive loss of disc height with progressive mild disc bulging. Along with prominent dorsal epidural fat, these findings contribute to a mild narrowing of the spinal canal but no evidence of nerve root impingement. Moderate right and mild left foraminal narrowing, progressed. L3-4: Facet hypertrophy. Progressive loss of disc height with slightly progressed disc bulging. Along with prominence of the dorsal epidural fat these findings contribute to a mild narrowing of the spinal canal but no evidence of nerve root impingement. Moderate right foraminal narrowing, progressed. Mild left foraminal narrowing, unchanged. L4-5: Facet hypertrophy and ligamentum flavum thickening. Mild disc bulging without significant change. Mild lateral recess narrowing and mild lateral foraminal narrowing, unchanged. L5-S1: Facet hypertrophy and ligamentum flavum thickening. Slight progressive loss of disc height with disc bulging and disc uncovering similar to prior. No significant spinal canal stenosis. Moderate to severe left and mild right neuroforaminal narrowing without change.
1.Grade 1 anterolisthesis of L5 relative to S1 with bilateral L5 spondylolysis, unchanged.2.Mild progression of degenerative disc disease at multiple levels as discussed above. These findings result in at most mild narrowing of the spinal canal, most notable at L2-3 and L3-4.3.Moderate to severe neuroforaminal narrowing at L5-S1 is unchanged. Scattered additional areas of mild to moderate foraminal narrowing are also seen as above.
