Paresthesias and back pain, rule out radiculopathy and myelopathy. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is some loss of lumbar lordosis and minimal retrolisthesis of L5 on S1. Alignment is otherwise normal. Bone marrow signal is benign. The conus medullaris is normal in position.Mild multilevel degenerative changes are seen with multilevel disc desiccation and mild height loss, relatively worse at the L5-S1 level. Individual levels as below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: Small extraforaminal disc protrusion which contacts the exiting left L2 nerve root. No spinal canal or neural foraminal stenosis. L3-L4: Small foraminal and extraforaminal disc protrusion which contacts and displaces the exiting left L3 nerve root in the foramen and extraforaminally. There is mild to moderate left-sided neural foraminal stenosis. No significant spinal canal or right neural foraminal stenosis. Mild facet arthropathy.L4-L5: Disc bulge and mild facet arthropathy. Mild to moderate left neural foraminal stenosis. There is mild right neural foraminal narrowing. No significant spinal canal stenosis.L5-S1: Disc bulge and mild bilateral facet arthropathy. No significant spinal canal stenosis. There is up to moderate right neural foraminal stenosis and mild to moderate left neural foraminal narrowing.Paraspinous soft tissues are within normal limits.
Multilevel degenerative changes in the lumbar spine. There is no significant spinal canal stenosis at any level. There is mild to moderate stenosis of the left neural neural foramina at the L3-L4, L4-L5, and L5-S1 levels. There is mild right L4-L5 and moderate right L5-S1 neural foraminal stenosis.
