Male, 73 years old, with numbness and paresthesia of the left big toe. Mild curvature of the lumbar spine is seen in the coronal plane. There is a grade 1 anterolisthesis of L4 relative to L5.The L2 vertebral body is compressed with approximately 50% loss of vertebral body height centrally. There is no associated marrow edema. The remaining vertebral bodies show preservation of height.Degenerative endplate signal abnormality is seen at L2-3. Elsewhere, marrow signal characteristics are unremarkable. No evidence of marrow edema is seen.The visualized distal spinal cord, conus and nerve roots of the cauda equina are unremarkable. No epidural abnormalities are suspected.T12-L1: Mild facet arthropathy and ligamentum flavum thickening. Mild bulging disc. No significant spinal canal or foraminal stenosis.L1-2: Mild facet arthropathy. Loss of disc T2 signal with preserved disc height. Minimal disc bulging. No significant spinal canal or foraminal stenosis. L2-3: Moderate facet arthropathy with bilateral facet effusions. Ligamentum flavum thickening. Loss of disc height with disc bulging and osteophytic spurring. The lateral recesses are narrowed but no significant generalized spinal canal stenosis is seen. The neural foramina are mildly narrowed. L3-4: Moderate facet arthropathy with bilateral facet effusions. Ligamentum flavum thickening. Loss of disc height and disc bulging. The lateral recesses are narrowed but there is no significant generalized spinal canal stenosis. Moderate right and mild left foraminal narrowing. L4-5: Advanced facet arthropathy and ligamentum flavum thickening. Loss of disc height and disc bulging. Effacement of both the dorsal and ventral thecal sac results in a mild to moderate generalized spinal canal narrowing. The descending L5 nerve roots may be somewhat impinged. Mild bilateral foraminal narrowing. L5-S1: Moderate facet arthropathy. Loss of disc height with disc bulging and a right paracentral/subarticular disc protrusion. As a result, the descending right S1 nerve root may be slightly impinged. No significant generalized spinal canal stenosis is seen. The neural foramina are not significantly narrowed.
1.Multilevel disc degeneration is seen. At L3-4, the lateral recesses are narrowed and there is a moderate right foraminal narrowing. At L4-5, there is a mild to moderate generalized spinal canal stenosis with possible impingement of the descending L5 nerve roots. At L5-S1, there is a right paracentral/subarticular disc protrusion which may impinge upon the descending right S1 nerve root.2.Facet arthropathy is seen at most levels. In addition, there is a compression deformity of the L2 vertebral body which is likely chronic given lack of marrow edema.
