Reason: lower extremity tingling - CNS process? History: tingling Vertebral body heights are intact. Minimal endplate degenerative marrow changes at T12-L1, otherwise no abnormal marrow signal. No abnormal enhancement. Multilevel disc desiccation with disc space loss, most severe at T11-T12, T12-L1 and L1-L2 No abnormal signal within the cord or conus which ends at L1. There is a levocurvature to the lumbar spine present.T12-L2: Moderate loss of disc height with diffuse disc bulge. No spinal canal or neural foraminal stenosis.L1-L2: Mild loss of disc height. Mild ligamentum flavum thickening and facet arthropathy. No spinal or neural foraminal stenosis.L2-L3: Small left lateral protrusion. Mild facet arthropathy and ligamentum flavum thickening. No spinal or neural foraminal stenosis.L3-L4: Mild diffuse disc bulge. Mild facet arthropathy and ligamentum flavum thickening. No spinal or neural foraminal stenosis.L4-L5: Mild diffuse disc bulge. Mild facet arthropathy and ligamentum flavum thickening. Mild anterior subluxation of L4 on L5. Mild spinal canal stenosis. No neural foraminal stenosis.L5-S1: Mild diffuse disc bulge. Mild facet arthropathy. No spinal canal stenosis. Mild left neural foraminal stenosis.Paraspinous musculature is atrophic. A small left renal cyst is present.
Multilevel spondylosis with mild narrowing of the canal at L4-L5 and mild left neural foraminal stenosis at L5-S1.
