Male, 67 years old, with right lower extremity weakness. Image quality is significantly degraded by motion artifact. Within this limitation the following observations are made.There is a grade 1 anterolisthesis of L4 relative to L5. The lumber spine is mildly scoliotic. Vertebral body heights are preserved. No evidence of marrow replacement or significant marrow edema is seen.Visualized spinal cord and conus are unremarkable. The nerve roots of the cauda equina are not well assessed due to motion artifact, but no significant abnormalities are suspected.L1-2: Facet hypertrophy and ligamentum flavum thickening. Mild bulging disk. No significant generalized spinal canal stenosis. Moderate right and mild left foraminal narrowing. L2-3: Facet hypertrophy and ligamentum flavum thickening. Bulging disk preferentially towards the neural foramina. No significant generalized spinal canal stenosis. Mild bilateral foraminal narrowing. L3-4: Facet hypertrophy and ligamentum flavum thickening. Bulging disk preferentially towards the neural foramina. No significant generalized spinal canal stenosis. Mild bilateral foraminal narrowing. L4-5: Facet hypertrophy and ligamentum flavum thickening. Bulging disk with effacement of the ventral thecal sac but no significant generalized spinal canal stenosis. Severe right neuroforaminal narrowing with nerve root impingement secondary to posterior element hypertrophy and disk degeneration. Mild left foraminal narrowing. L5-S1: Mild facet hypertrophy. Mild bulging disk. No significant spinal canal stenosis. Mild right neuroforaminal narrowing.
1. Significantly limited examination due to motion artifact.2. Multilevel degenerative findings, most severely affecting the L4-5 level, where there is a bulging disk and posterior element hypertrophy which result in severe narrowing of the right L4-5 neural foramen with probable nerve impingement.
