Right-sided low back pain with sciatica and history of herniated disc on prior imaging 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.Multilevel 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: There is a disc bulge eccentric to the left and a left paracentral disc protrusion which effaces the left lateral recess and may be impinging on the descending left L4 nerve root. No significant central spinal canal stenosis. There is minimal narrowing of the neural foramina.L4-L5: There is a larger right central disc protrusion which effaces the right lateral recess where there may be impingement of the descending right L5 nerve root. There is also a disc bulge with a left foraminal component. No significant central spinal canal stenosis. There is mild left and minimal right neural foraminal narrowing. L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
1. Disc protrusions at the left L3-L4 and right L4-L5 levels which may be impinging on the left L4 and right L5 nerve roots in the lateral recesses, respectively.2. No significant central spinal canal stenosis at any level. There is mild left L4-L5 neural foraminal stenosis. No high-grade neural foraminal stenosis at any level. Additional details as above.
