 At L5-S1, there is desiccation of the intervertebral disc with mild loss of intervertebral disc height and a disc bulge causing moderate to severe right and moderate left compression of the traversing S1 nerve roots, but no significant neural foraminal narrowing. Otherwise, there is no significant disc bulge, herniation, spinal canal, foraminal stenosis or facet disease at T12 through L5. The lumbar spine displays a normal lordosis. The vertebral body heights are maintained. The bone marrow signal is unremarkable. The distal spinal cord and conus medullaris are within normal limits. The paravertebral soft tissues are unremarkable.
A disc bulge at L5-S1 results in bilateral lateral recess stenosis with nerve root compression, right more than left.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
