Lumbar back pain Five lumbar type vertebral bodies are presumed to be present. S1 appears to demonstrate transitional anatomy with lumbarization on the right, which can be better visualized with radiographs or CT. 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.L5-S1: There is disc desiccation with dorsal annular fissure and tiny central protrusion. There is no significant spinal canal or neural foraminal stenosis. Paraspinous soft tissues are within normal limits. There is an approximately 1 cm cystic lesion involving the subcutaneous tissues of the back on the left at the L2-L3 level, which may represent a sebaceous cyst.
Mild degenerative changes at the L5-S1 level with dorsal annular fissure and small central disc protrusion. There is no significant spinal canal stenosis or neural foraminal stenosis at any level.
