Right lumbar back pain radiating to the foot, not improving with PT. There is an eccentric right disc extrusion at L5-S1 that measures up to 2 cm in the anteroposterior dimension and is associated with compression of the cauda equina nerve roots in the right lateral recess and mild right L5-S1 neural foramen stenosis. There is no significant disc disease involving the other levels of the lumbar spine. The vertebral column alignment is within normal limits. The vertebral body heights are preserved. The vertebral bone marrow signal is unremarkable. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable.
