 For the purposes of numbering, there are 5 lumbar type vertebral bodies. Vertebral body heights are maintained. Alignment is maintained. Note is made of a subtle linear defect within the right L1 transverse process which is not well evaluated on MRI but may represent a remote fracture. There is general disc desiccation at most lumbar levels which is worse at the L5-S1 level. The cord signal is normal and the cord terminates normally at the L1-L2 level.Multilevel degenerative changes are seen, as describe below:At L1-2 there is no significant compromise to spinal canal or neural foramina.At L2-3 there is mild facet degenerative changes and mild ligamentum flavum hypertrophy. No significant compromise to spinal canal or neural foramina.At L3-4 there is mild facet degenerative changes and mild ligamentum flavum hypertrophy with minimal right neuroforaminal stenosis. There is no significant compromise to spinal canal or left neural foramen.At L4-5 there is a mild disc protrusion and mild to moderate degenerative changes and ligamentum flavum hypertrophy which causes minimal bilateral neural foraminal stenosis. There is no significant compromise to spinal canal.At L5-S1 there is a mild disc protrusion as well as advanced facet degenerative changes and ligamentum flavum hypertrophy which cause moderate to severe right and mild to moderate left neuroforaminal stenosis. There is no significant compromise to spinal canal. A small synovial cyst is noted posterior to the left L5-S1 facet joint.The paraspinous soft tissues are within normal limits.
Degenerative changes involving the lumbar spine, worse at the L5-S1 level where there are advanced facet degenerative changes and ligamentum flavum hypertrophy, which result in moderate to severe right neuroforaminal stenosis and possible impingement of the exiting right L5 nerve root. Individual levels as above. No significant spinal canal stenosis at any level.
