Low back pain, history of herniated disk and lumbar radiculopathy. There is an eccentric left disc protrusion at L5-S1 that results in mild-to-moderate left neural foraminal stenosis, but no significant right neural foraminal or spinal canal stenosis. There is slight disc bulge at L4-5 with minimal left neural foraminal stenosis. There are fatty and edematous degenerative endplate signal alterations at L4-5 and L5-S1 with loss of fluid signal and loss of height of the discs. There is no significant degenerative spondylosis at the other lumbar spine levels. The vertebral column alignment is within normal limits. The vertebral body are preserved. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable, aside from mild dependent edema in the posterior subcutaneous tissues.
Mild-to-moderate left L5-S1 neural foraminal stenosis related to a disc protrusion.
