Reason: history of L4-5 disc herniation, now with pain and urinary retention History: as above Vertebral body heights are within normal limits. Alignment is within normal limits. No abnormal marrow signal. No abnormal signal within the cord or conus which ends at T12-L1.T12-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. Mild ligamentum flavum thickening. No spinal canal or neural foraminal stenosis.L3-L4: No significant disc disease. Mild facet arthropathy on the left. Mild ligamentum flavum thickening. No spinal canal or neural foraminal stenosis.L4-L5: Small central extrusion extending inferiorly. Facet arthropathy bilaterally. Mild ligamentum flavum thickening. No spinal canal or neural foraminal stenosis.L5-S1: Right foraminal protrusion producing mild right neuroforaminal narrowing. Mild bilateral facet arthropathy. No significant spinal canal stenosis.Paraspinous soft tissues are within normal limits.
1.Mild degenerative changes in the lumbar spine at the L4-L5 and L5-S1 levels. No significant spinal canal stenosis at any level to suggest compression of the cauda equina nerve roots.2.Small central extrusion at L4-L5 without significant spinal canal or neural foraminal stenosis.3.Small right foraminal protrusion at L5-S1 producing mild right neural foraminal narrowing.
