History of lumbar laminectomy 2006 with recurrent left lumbar radiculopathy. There is loss of fluid signal and height of the L4-5 disc with associated annular fissuring and an eccentric left disc extrusion that impinges upon the descending nerve roots in the left lateral recess. There is slight narrowing of the left neural foramen. There is bilateral facet hypertrophy at L3-4 and L5-S1 without significant spinal canal or neural foraminal narrowing. There are no significant degenerative changes involving T12 through L3. The imaged portions of the spinal cord are unremarkable. The vertebral column alignment is within normal limits. The vertebral body heights are preserved. The vertebral bone marrow signal is unremarkable. The paravertebral soft tissues are unremarkable.
Degenerative spondylosis at L4-5 with impingement upon the descending nerve roots in the left lateral recess.
