Female, 79 years old, with lumbar stenosis. All lumbar vertebral bodies demonstrate some degree of height loss. L1 is most severely affected with near complete loss of height centrally. L4 is the next most severely affected with approximately 70% loss of height. These findings are similar to prior.A kyphotic angulation of the spine is seen centered at L1. Stepwise mild retrolistheses of L2 on L3, L3 on L4, and L4 on L5 are seen, similar to prior.Marrow signal characteristics are heterogeneous and there is evidence of mild edema within the L1 vertebral body and along the endplates of L3-L5, likely degenerative in nature. Findings are unchanged. No worrisome marrow replacement is detected.The visualized spinal cord and conus are unremarkable. Details of the cauda equina are discussed below.With the exception of L1-2 and L5-S1, the intervertebral discs show severe loss of height. Additional level specific findings are as follows:T12-L1: Facet hypertrophy and ligamentum flavum thickening. Disc bulging, osteophytic spurring and mild vertebral body retropulsion. Mild generalized spinal canal stenosis. Mild foraminal narrowing. No significant interval changes.L1-2: Bulging disc asymmetric to the right. No significant spinal canal stenosis. Mild right foraminal narrowing. No interval changes. L2-3: Facet hypertrophy and ligamentum flavum thickening. Disc bulging and osteophytic spurring, asymmetric to the right. No significant generalized spinal canal stenosis. Moderate right and mild left foraminal narrowing. No significant interval changes.L3-4: Facet hypertrophy and ligamentum flavum thickening. Bulging disc and osteophytic spurring. Moderate to severe spinal canal narrowing with some crowding of the cauda equina. Moderate right and mild left foraminal narrowing. No significant interval changes.L4-5: Severe facet hypertrophy and ligamentum flavum thickening. Bulging disc and osteophytic spurring. Severe spinal canal stenosis with crowding and probable impingement of the cauda equina. Severe right and moderate left foraminal narrowing. No interval changes. L5-S1: Severe facet hypertrophy and ligamentum flavum thickening. Bulging disc. Moderate generalized spinal canal stenosis. No significant neuroforaminal narrowing. No significant interval changes.
1.No significant change in multilevel vertebral body compression deformities, most severely affecting L1 and L4.2.No significant change in severe disc degeneration with relatively severe spinal canal stenoses and right-sided foraminal narrowing at L3-4 and L4-5.
