Lumbar stenosis. Low back pain with bilateral leg radiation. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are grossly maintained aside from mild anterior compression deformities involving the L1 and L3 vertebral bodies, without edema. There is also mild levocurvature of the distal thoracic spine and mild levocurvature of the lumbar spine as seen on the coronal localizer sequence. There is mild reversal of lumbar lordosis. Bone marrow signal is benign with mild edematous marrow signal changes evident at L4-L5 and to a lesser degree at additional levels superiorly and inferiorly. The conus medullaris is normal in position at the L1-L2 level. Vacuum disc phenomena is noted at multiple levels.Multilevel degenerative changes are seen throughout the spine, as described below:T11-T12: Mild disc bulge, ligamentum flavum thickening, and prominent facet arthropathy. There is mild to moderate spinal canal stenosis with subtle T2 hyperintensity in the left ventral aspect of the cord at this level suspected. There is severe right neural foraminal stenosis.T12-L1: No significant spinal canal or neural foraminal stenosis. Ligamentum flavum thickening and facet arthropathy.L1-L2: There is severe spinal canal stenosis related to disc bulge, facet arthropathy, ligamentum flavum thickening, and prominence of the dorsal epidural fat. There is mild to moderate bilateral, right greater than left, neural foraminal stenosis.L2-L3: There is severe spinal canal stenosis related to disc bulge, facet arthropathy, and ligamentum flavum thickening, particularly the right aspect of the spinal canal. There is effacement of the lateral recesses, right greater left. There is mild right and mild to moderate left neural foraminal stenosis.L3-L4: There is severe spinal canal stenosis related to disc bulge, facet arthropathy, and ligamentum flavum thickening. There is mild to moderate right and severe left neural foraminal stenosis. L4-L5: There is severe spinal canal stenosis related to disc bulge, facet arthropathy, and ligamentum flavum thickening. Bilateral lateral recesses are effaced. There is moderate right and moderate to severe left neural foraminal stenosis.L5-S1: There is disc osteophyte complex which effaces the left S1 root in the lateral recess. There is no significant central canal stenosis otherwise. There is moderate to severe bilateral neural foraminal stenosis. There is an abdominal aortic aneurysm which is partially imaged.
1. Advanced degenerative changes throughout the lumbar spine with severe spinal canal stenosis from L1-L2 to the L4-L5 levels. There is also effacement of the left lateral recess at the L5-S1 level although there is no significant central canal stenosis at this level. 2. There is also mild to moderate spinal canal stenosis at the T11-T12 level. Subtle T2 signal abnormality in the left aspect of the cord is suspected.3. Multilevel neural foraminal stenoses as detailed above.4. Mild anterior wedging of the L1 and L3 vertebral bodies compatible with mild chronic compression fractures. No associated edema.5. Partially imaged abdominal aortic aneurysm.
