Lumbar radiculopathy. Right leg pain. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is mild straightening of the lumbar spinal curvature which may be in part positional. Alignment is otherwise within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.Minimal degenerative changes are seen, 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: Minimal disc bulge. No spinal canal or neural foraminal stenosis.L4-L5: Minimal disc bulge with annular fissures involving the foraminal aspects of the disc bilaterally. There is also a small right foraminal disc protrusion best seen on image 12 of sagittal T2 and sagittal STIR sequences. There is mild right neural foraminal stenosis and contact of the exiting L4 nerve root. No clear evidence of impingement however. Otherwise no significant spinal canal or neural foraminal stenosis.L5-S1: Minimal disc bulge. No spinal canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
There is a subtle right foraminal disc protrusion involving the L4-L5 level. There is contact of the exiting right L4 nerve root without clear evidence of impingement and can be correlated with clinical findings. There is otherwise no significant spinal canal or neural foraminal stenosis at any level.
