Low back pain radiating to right thigh Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is benign. There is edema involving the L5 pedicles likely related to facet arthropathy. The conus medullaris is normal in position. Small Schmorl's node is noted involving the superior endplate of L2.Lumbar spinal canal appears mildly narrowed on a congenital basis with superimposed prominence of the epidural fat and degenerative changes as described below: L1-L2: Mild disc bulge and facet arthropathy. No significant spinal canal or neural foraminal stenosis.L2-L3: Mild disc bulge and bilateral facet arthropathy. There is minimal spinal canal narrowing. No significant neural foraminal narrowing.L3-L4: There is disc bulge, ligamentum flavum thickening, facet arthropathy, and prominence of the epidural fat which results in mild spinal canal stenosis. There is mild to moderate right and mild left neural foraminal stenosis.L4-L5: There is disc bulge eccentric to the right, with ligamentum flavum thickening and advanced bilateral facet arthropathy. There is effacement of the lateral recesses as well as mild to moderate central spinal canal stenosis. There is moderate right neural foraminal stenosis and possible impingement of the exiting right L4 nerve root. Mild left neural foraminal stenosis.L5-S1: There is disc bulge and advanced bilateral facet arthropathy. There is partial effacement of the lateral recesses without significant central spinal canal stenosis. There is mild right and mild to moderate left neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
1. Degenerative changes throughout the lumbar spine as detailed above, worst at the L4-L5 level. There is mild to moderate spinal canal stenosis at this level and moderate right neural foraminal stenosis, which may be impinging on the exiting right L4 nerve root.2. Advanced bilateral facet arthropathy at L4-L5 and L5-S1 which may be contributing to patient's low back pain.
