 There are postoperative changes at L4 and L5. There is disc desiccation at all levels. The vertebral column alignment is within normal limits. The vertebral body heights are preserved. With the exception of endplate degenerative change, the vertebral bone marrow signal is unremarkable. The imaged spinal cord displays normal signal and morphology and the conus terminates at L1-L2. The paravertebral soft tissues are unremarkable.L1-L2: There is an unchanged minimal disc bulge as well as bilateral facet arthropathy and ligamentum flavum thickening. There is no significant spinal canal or neural foramen stenosis.L2-L3: There is an unchanged mild disc bulge asymmetric to the left as well as bilateral facet arthropathy and ligamentum flavum thickening that is mildly progressed as well as ligamentum flavum thickening. These findings result in minimally worsened mild spinal canal stenosis and impingement upon the right subarticular zone.L3-L4: There is unchanged loss of disc height, modic type 2 endplate degenerative changes, and a slightly enlarged moderately sized disc bulge as well as bilateral facet arthropathy and ligamentum flavum thickening. Findings result in unchanged moderate spinal canal stenosis and unchanged severe right and moderate left neural foramen stenosis.L4-L5: There is unchanged loss of disc height, modic type 2 endplate degenerative changes and a moderately sized disc bulge as well as a small unchanged annular fissure. There is severe bilateral facet arthropathy that is mildly progressed as well as ligamentum flavum thickening. These findings result in mildly progressed severe spinal canal stenosis as well as severe right and moderate left neural foramen stenosis.L5-S1: There is an unchanged mild disc bulge as well as bilateral facet arthropathy. Findings result in unchanged severe left and moderate right neural foramen stenosis and no significant spinal canal stenosis.
Slightly progressed multilevel severe degenerative changes including up to severe spinal canal stenosis at L4-L5, multilevel moderate and severe neural foramen stenosis, and severe multilevel facet arthropathy.
