Left lower extremity weakness. Evaluate for spinal stenosis. 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. The conus medullaris is normal in position.Mild 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: No significant disc disease. No spinal canal or neural foraminal stenosis.L4-L5: No significant disc disease. No spinal canal or neural foraminal stenosis. Mild facet arthropathy.L5-S1: There is disk desiccation and mild bulge. Mild facet arthropathy. There is minimal bilateral neural foraminal narrowing, right relatively worse than left. No significant spinal canal stenosis. Incidentally seen are multiple small perineural cysts in the lumbar spine, lower thoracic spine, as well as in the sacrum. Relatively largest of these is along the right S2 nerve root measuring approximately 2 cm. Paraspinous soft tissues are within normal limits.
1. Mild degenerative changes in the lumbar spine without significant spinal canal stenosis at any level. There is minimal narrowing of the bilateral L5-S1 neural foramina, right relatively worse than left; otherwise no significant neural foraminal narrowing in the lumbar spine. 2. Mild facet arthropathy at L4-5 and L5-S1.3. Multiple small perineural cysts are noted which are of doubtful clinical significance.
