MRI lumbar spine w/wo contrast - shows normal conus medullaris. No unusual contrast enhancement through the cauda equina or proximal nerve roots to suggest neuromyelitis. Multilevel lumbar foraminal stenosis. Clumping of the nerve roots at L3-L4 is a nonspecific finding. There is no contrast enhancement or focal mass. This may be evidence of scarring from focal arachnoiditis. Degenerative disc disease throughout the upper lumbar spine consists primarily of anterior osteophyte formation. No disc herniation.
