Night times back pain, lower extremity numbness. 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.Individual levels 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.L5-S1: There is a disc bulge with central disc protrusion without significant central spinal canal stenosis. There is mild left neural foraminal stenosis. Right neural foramen is patent. There is also a Schmorl's node involving the posterior superior S1 vertebral body endplate with mild adjacent edema.Paraspinous soft tissues are within normal limits.
1. L5-S1 disc protrusion without significant central spinal canal stenosis. There is mild left neural foraminal stenosis. There is also intravertebral herniation (Schmorl's node) involving the superior endplate of the S1 vertebral body with mild surrounding edema.2. No significant disc disease, spinal canal or neural foraminal stenosis in the remainder of the lumbar spine.
