Low back pain, L4-L5, more right-sided symptoms. Five lumbar type vertebral bodies are presumed to be present. There is severely diminished disc height at L5-S1 and to a slightly lesser degree at L4-L5. Alignment is within normal limits. Bone marrow signal is benign with fatty endplate changes at L4-5 and L5-S1. The conus medullaris is normal in position. Mild T12-L1 disc bulge.Multilevel degenerative changes are seen in the lumbar spine, as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: No significant disc disease. No spinal canal or neural foraminal stenosis.L4-L5: Severe loss of disc height. Minimal disc bulge with small mall left sided annular fissure. Ligamentum flavum thickening and mild facet arthropathy result in mild narrowing of the thecal sac in the transverse dimension. Minimal left neural foraminal stenosis. No right neural foraminal stenosis.L5-S1: No significant disc disease. No spinal canal stenosis. Mild bilateral neural foraminal stenosis related to endplate osteophytes which contact the exiting L5 nerve roots. Mild facet arthropathy.Paraspinous soft tissues are within normal limits. Tiny perineural cysts incidentally noted. Ectopic right kidney in the pelvis incidentally noted.
Degenerative changes at L4-L5 and L5-S1 with severe loss of disc height at these levels. Mild L4-L5 spinal canal narrowing and mild L5-S1 bilateral neural foraminal stenosis. No high-grade spinal canal or high-grade neural foraminal stenosis at any level.
