 There is a rudimentary disk at S1-S2. The lumbar spine is in normal alignment, with a normal lumbar lordosis. Redemonstrated is multilevel disk narrowing and desiccation, most prominent at L5-S1 where there is moderate narrowing. The vertebral body heights are well-maintained. The distal spinal cord and conus are within normal limits with the conus terminating at the mid L2 level. No worrisome focal marrow signal abnormality is appreciated. There are endplate degenerative changes on the right at T10-T11. There is narrowing of the distal lumbar spinal canal predominantly due to shortened pedicles. There is thickening and slight redundancy of the cauda equina nerve root relating to spinal stenosis to be detailed below.New T2 signal is seen within the right paraspinal musculature at the level of S1 through S3 (best seen series 5, images 2/17 through 7/17).At T10-T11 and T11-T12, sagittal images suggest a mild diffuse disk bulge with right sided moderate foraminal narrowing. There may be mild central spinal canal stenosis. These findings are unchanged.At T12-L1, there is a mild diffuse disk bulge without stenosis, unchanged.At L1-L2, there is a mild diffuse disk bulge resulting in mild-moderate right and moderate left foraminal narrowing, unchanged.At L2-L3, there is a shallow right foraminal disk protrusion without stenosis, unchanged.At L3-L4, there is a trace diffuse disk bulge with mild left facet arthropathy. There is mild developmental narrowing of the lumbar spinal canal with overall moderate central spinal canal stenosis. There is also mild bilateral lateral recess stenosis as well as minimal right and moderate left foraminal narrowing. These findings are unchanged.At L4-L5, there is a mild diffuse disk bulge with left paracentral prominence. There is also prominent facet arthropathy and ligamentum flavum thickening. Superimposed upon the developmental narrowing, there is moderate-severe central spinal canal stenosis, moderate bilateral lateral recess stenosis as well as moderate left and mild-moderate right foraminal narrowing. These findings are unchanged.At L5-S1, there is a diffuse disk bulge with bilateral facet arthropathy and ligamentum flavum thickening. There is mild-moderate central spinal canal stenosis, although there is moderate-severe bilateral foraminal narrowing. These findings are unchanged.
1.New T2 signal is seen within the right paraspinal musculature at the level of S1 through S3. This appearance is most suggestive of muscle strain or other soft tissue injury.2.Multilevel degenerative disease with stenoses, stable in appearance, as described in detail above on a level by level basis.
