Buttock pain with left leg radiculopathy and weakness in left leg Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is loss of lumbar lordosis. Alignment is otherwise maintained. Bone marrow signal is benign. The conus medullaris is normal in position.Multilevel degenerative changes are seen, as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: Disc desiccation and mild bulge. No spinal canal or neural foraminal stenosis.L3-L4: Disc desiccation and mild bulge. No spinal canal or neural foraminal stenosis.L4-L5: There is disc bulge eccentric to the left without significant spinal canal stenosis. Previously seen left foraminal and extraforaminal disc protrusion is slightly less prominent and the previously seen annular fissure is no longer appreciated. There is mild left neural foraminal stenosis with contact of the exiting left L4 nerve root. No significant right neural foraminal narrowing. L5-S1: Disc desiccation, loss of height, and mild bulge. No spinal canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
1. Disc bulge eccentric to the left at the L4-L5 level which contacts the exiting left L4 nerve root. There is mild left-sided neural foraminal stenosis which was also present on prior study from 2004.2. Remainder of the spinal canal or neural foramina are patent.
