Low back pain. There is a 15 mm thick disc central extrusion at L4-5 that result in severe spinal canal stenosis with compression of the cauda equina nerve roots, but no significant neural foramen stenosis. There is also a 9 mm thick eccentric right disc extrusion at L3-4 with effacement of the right lateral recess with compression of the adjacent nerve roots, but no significant neural foramen stenosis. There is no significant spinal canal stenosis at the other levels of the lumbar spine. The vertebral column alignment is within normal limits. The vertebral body are preserved. The vertebral bone marrow signal is unremarkable. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable.
