Female, 72 years old, status post lumbar surgery with right greater trochanter pain. Assess for stenosis. A grade 2 anterolisthesis of L4 relative to L5 has mildly progressed from prior. Otherwise spinal alignment is anatomic. No worrisome marrow replacement, edema or enhancement is seen.The visualized spinal cord, conus and nerve roots of cauda equina are unremarkable except as discussed below. No pathologic intracanalicular enhancement is seen.L1-2: Mild facet hypertrophy. No significant spinal canal or neuroforaminal stenosis. No significant interval changes. L2-3: Mild facet hypertrophy. No significant spinal canal or neuroforaminal stenosis. No significant interval changes. L3-4: Moderate facet hypertrophy and ligamentum flavum thickening. Mild bulging disk. No significant generalized spinal canal stenosis. Mild bilateral foraminal narrowing. No significant interval changes.L4-5: Marked facet hypertrophy with inflammation of the surrounding soft tissues. Marked ligamentum flavum thickening. Spondylolisthesis, mildly progressed, with disc uncovering and disc bulging. Moderate to severe generalized spinal canal stenosis with crowding of the cauda equina nerve roots, not significantly changed. Moderate left and severe right foraminal narrowing, not significantly changed. L5-S1: Moderate facet hypertrophy. Minimal bulging disc. No significant spinal canal stenosis. Mild bilateral foraminal narrowing. No significant interval changes.
1.Slight progression of spondylolisthesis at L4-5. Moderate to severe generalized spinal canal stenosis at this level, along with severe right and moderate left foraminal narrowing, not significantly changed.2.Mild degenerative findings at the remaining levels are not significantly changed.
