Leg pain, history of disc herniation surgery in 2006 Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is loss of lumbar lordosis as well as minimal retrolisthesis of L5 on S1. Alignment is otherwise maintained. Bone marrow signal is benign. The conus medullaris is normal in position.There appears to be mild developmental narrowing of the spinal canal. There are multilevel degenerative changes as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: There is disc desiccation and minimal bulge without spinal canal or neural foraminal stenosis.L4-L5: There is disc desiccation and mild bulge, and central dorsal annular fissure. Mild distention of the facet joints. No significant spinal canal or neural foraminal narrowing. L5-S1: There is severe loss of disc height and prominent Schmorl's node anteriorly. There is a disc bulge with a right paracentral disc protrusion component which effaces the right lateral recess and where there may be impingement of the right S1 nerve root. There is also partial effacement of the left lateral recess. No significant central canal stenosis. There is moderate to severe bilateral neural foraminal stenosis. There is evidence of prior right sided laminotomy.Atrophic native kidneys with cysts noted. Left lower quadrant presumed transplant kidney partially imaged.
1. Multilevel degenerative changes, particularly at the L5-S1 level where there is severe loss of disc height and a right paracentral disc protrusion which effaces the right lateral recess. There is also moderate to severe bilateral neural foraminal stenoses at this level. No significant central canal stenosis at any level.2. Postsurgical changes of right L5-S1 laminotomy.
