Weakness, frequent falls, low back pain. Evaluate for stenosis. Thoracic: Vertebral body heights in the thoracic spine are normal. Alignment is maintained. Bone marrow signal is benign with T1 hyperintense lesion in the T11 vertebral body consistent with a hemangioma. Mild degenerative changes are seen in the thoracic spine. There is a small central disc protrusion at the T5-T6 level without significant stenosis. There is also mild disc bulge at the T11-T12 level without significant stenosis. There is facet arthropathy at the T8-T9 level with mild left greater than right neural foraminal stenosis. No significant neural foraminal stenosis at the other levels. Mild facet arthropathy is also seen in the lower lumbar spine. No abnormal signal in the thoracic cord. No significant spinal canal stenosis at any level in the thoracic spine.Lumbar: Five lumbar type vertebral bodies are presumed to be present. There is transitional anatomy with lumbarization of the S1 vertebral body with well-defined disc space at the S1-S2 level. Vertebral body heights are within normal limits. There appears to be levoscoliosis involving the lower lumbar spine which can be better evaluated with radiographs. Bone marrow signal is benign with fatty endplate signal changes at L3-L4 and L4-L5 on a degenerative basis. The conus medullaris is normal in position.Multilevel degenerative changes are seen, as described below:L1-L2: Minimal disc bulge. No spinal canal or neural foraminal stenosis.L2-L3: Minimal disc bulge and mild facet arthropathy. No spinal canal or neural foraminal stenosis.L3-L4: Moderate loss of disc height. There is a right paracentral disc extrusion. Bilateral facet arthropathy and ligamentum flavum thickening. There is moderate spinal canal stenosis at this level. There is moderate right and minimal left neural foraminal stenosis. L4-L5: Moderate loss of disc height and mild bulge. There is advanced bilateral facet arthropathy and ligamentum flavum thickening. There is mild to moderate degree of spinal canal stenosis. There is moderate to severe right and moderate left neural foraminal stenosis.L5-S1: There is mild disc bulge and bilateral facet arthropathy, severe on the left. There is partial effacement of the left lateral recess. No significant central canal stenosis. There is mild left greater than right neural foraminal stenosis.S1-S2: No significant disc disease. No spinal canal or neural foraminal stenosis.
1. Mild degenerative changes in the thoracic spine without significant spinal canal stenosis at any level. No cord signal abnormality.2. Moderate degenerative changes in the lumbar spine with moderate spinal canal stenosis at L3-L4 and to a slightly lesser degree spinal canal stenosis at L4-L5. Neural foraminal stenosis is worst at the L4-L5 level. Please see details above.3. Transitional lumbosacral anatomy as detailed above.
