Female, 70 years old, with left leg weakness. Assess for stenosis. Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. Degenerative endplate signal alteration is seen at L5-S1. Otherwise, no worrisome marrow signal abnormality is detected.The visualized spinal cord, conus and nerve roots of the cauda equina are within normal limits.The intervertebral discs demonstrate loss of T2 signal. In addition, there is moderate loss of disc height at L5-S1. Additional level specific findings are as follows:L1-2: No significant spinal canal or neuroforaminal stenosis. L2-3: Minimal bilateral foraminal disc bulging. No significant spinal canal stenosis. Mild bilateral foraminal narrowing. L3-4: Mild facet hypertrophy and ligamentum flavum thickening. Minimal bilateral foraminal disc bulge. No significant spinal canal stenosis. Moderate right and mild left foraminal narrowing. L4-5: Severe right and moderate left facet hypertrophy. Mild ligamentum flavum thickening. Bulging disc with small superimposed left paracentral and right foraminal protrusions. Mild generalized spinal canal narrowing. Mild right foraminal narrowing. L5-S1: Moderate bilateral facet hypertrophy. Mild bulging disc. No significant spinal canal stenosis. Severe bilateral foraminal narrowing.
1.Mild generalized spinal canal stenosis at L4-5. No other significant spinal canal compromise is identified.2.Severe bilateral foraminal narrowing at L5-S1. Moderate foraminal narrowing on the right at L3-4.
