 The last well formed disk space is referred to as L5-S1. There is disk desiccation and L2-3 and L5-S1 with mild loss of disk height. The conus terminates in L2, within normal limits. The vertebral body heights and alignment is preserved. There is no osseous marrow edema.T12-L1: No disk herniation or spinal stenosis.L1-2: No disk herniation or spinal stenosis.L2-3: Minimal disk bulge, facet arthropathy and ligament flava thickening causing minimal bilateral neural foraminal narrowing. No significant spinal stenosis.L3-4: Mild disk bulge, left foraminal protrusion and annular fissure, ligamenta flava thickening and facet hypertrophy causing severe left and mild right neural foraminal stenosis. No spinal canal stenosis.L4-5: Mild disk bulge asymmetric to the left, facet arthrosis and ligamenta flava thickening causing moderate to severe left neural foraminal stenosis and mild right neural foraminal stenosis. No spinal canal stenosis.L5-S1: Disk bulge with small central disk protrusion and annular fissure, and mild bilateral facet arthrosis causing moderate left neural foraminal stenosis. No spinal canal stenosis.There is mild increased T2 signal in the left posterior paraspinal musculature best seen on series 7 image 3, and series 8 images 45 -- 50. There may be minimal volume loss of the effect of musculature as well.
1.Multilevel lumbar spondylosis as described above with areas of mild to marked neural foraminal stenoses. No spinal canal stenosis.2.Mild increased T2 signal and atrophy of the left posterior paraspinal musculature at the level of L5 and sacrum, nonspecific. This maybe secondary to muscle strain/spasm, less likely a denervation effect.
