Possible right L5 herniated disc 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. Low T1 and T2 signal focus at the right S2 level may represent a sclerotic lesion such as bone island. 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 significant spinal canal or neural foraminal stenosis.L3-L4: Disc desiccation and mild bulge, eccentric to the left. There is mild narrowing of the neural foramina, left relatively greater than right. There is contact of the extraforaminal left L3 nerve root. No spinal canal stenosis.L4-L5: There is a disc bulge with a central protrusion. There is no significant spinal canal or neural foraminal stenosis.L5-S1: There is a relatively large right paracentral disc protrusion which contacts the descending right S1 nerve root. The neural foramina and central canal remain patent. Paraspinous soft tissues are within normal limits.
Mild degenerative changes in the lumbar spine. There is a right paracentral disc protrusion at the L5-S1 level which may be impinging on the right S1 nerve root. Additional levels of degenerative disease as described above.
