Low back pain and radiation of pain down the right lower extremity. There is disc dessication with loss of height and slight disc bulging at L5-S1, as well as ligamentum flavum thickening and facet hypertrophy with trace joint effusions, which result in mild bilateral neural foraminal narrowing. There is also facet and ligamentum flavum hypertrophy at L4-5, with mild bilateral neural foraminal narrowing, but no significant spinal canal stenosis. Otherwise, there is no significant degenerative disease at T12 through L4. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable.
