Female, 88 years old, with low back pain and leg pain subacute and worsening over 10 years. Trace anterolisthesis of L2 relative to L3, and L3 relative to L4, is demonstrated. Otherwise, spinal alignment is anatomic.Vertebral body heights are preserved. With the exception of scattered endplate degenerative change, most notable at L5-S1, marrow signal characteristics are within normal limits.The visualized distal spinal cord, conus and nerve roots of the cauda equina are unremarkable. No epidural abnormalities are suspected.Bilateral renal cysts are present. However, on the left, there is a very large cyst which is likely renal in origin, significantly increased in size from anything seen on the prior CT, but only partially visualized on this examination.L1-2: No significant spinal canal stenosis or neuroforaminal narrowing. L2-3: Facet arthropathy and ligamentum flavum thickening. Mild disc bulging. Mild spinal canal stenosis. Mild bilateral foraminal narrowing. L3-4: Facet arthropathy and ligamentum flavum thickening. Minimal disc bulging. No significant spinal canal stenosis. No significant foraminal narrowing. L4-5: Facet arthropathy and ligamentum flavum thickening. Mild disc bulging. Mild spinal canal narrowing. No significant foraminal narrowing. L5-S1: Facet arthropathy. Minimal disc bulging. No spinal canal stenosis. Moderate left and mild right foraminal narrowing.
1.Relatively mild degenerative findings are demonstrated. These result in mild spinal canal stenosis at L2-3 and L4-5, and moderate left foraminal narrowing at L5-S1.2.Interval significant increase in the size of a partially visualized left abdominal cystic lesion, possibly renal in origin. Dedicated abdominal imaging should be considered.
