History of bulging disc 2 year ago: back pain - radicular to both legs to thigh - worse on left. There is a persistent eccentric right disc extrusion with annular fissuring that narrows the right lateral recess at the L5-S1 level, where nerve roots are compressed. There is minimal facet hypertrophy and ligamentum flavum thickening at this level. There are small bilateral neural foraminal perineural cysts at L5-S1. There is also a new small eccentric right disc protrusion with annular fissuring at the L3-4 level without significant spinal canal or neural foraminal narrowing. There is no significant degenerative spondylosis at T12-L1, L1-2, L2-3, and L4-5. 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.
