Left radiculopathy, status post fusion Five lumbar type vertebral bodies are presumed to be present. There are postsurgical changes of partial corpectomy at L1 with cage placed as well as posterior spinal instrumentation including paraspinous rods and pedicle screws, which extend from T11 to L3. Bony bridging and hardware integrity is better assess on prior radiographs. The conus medullaris is normal in position at the mid to lower L2 level. There is mild clumping of the cauda equina nerve roots at L1-L2 suggesting arachnoiditis.Susceptibility artifact from hardware limits evaluation. There appears to be focal marrow signal abnormality involving the residual L1 vertebral body. Otherwise no large lesions are appreciated. There is loss of normal lumbar lordosis with mild focal lordotic angulation at the L1 level. There is grade 1 anterolisthesis of L3 on L4.Individual levels as below:L1-L2: No spinal canal or neural foraminal stenosis. L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: There is grade 1 anterolisthesis. There is a left foraminal disc extrusion with mild cranial migration. There is moderate to severe left neural foraminal stenosis with suspected impingement of the exiting left L3 nerve root. Spinal canal and right neural foramen are patent. There is advanced bilateral facet arthropathy.L4-L5: Mild disc bulge, which is eccentric to the right. No spinal canal stenosis. There is mild right neural foraminal stenosis. Left neural foramen is patent. Moderate bilateral facet arthropathy.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis. Mild bilateral facet arthropathy.Paraspinous soft tissues are within normal limits.
1. Postsurgical changes of L1 partial corpectomy with placement of cage and posterior spinal fusion from T11 to L3.2. At L3-L4, there is a disc extrusion involving the left neural foramen, with associated suspected impingement of the exiting left L3 nerve root. There is also advanced facet arthropathy at this level and grade 1 anterolisthesis. Additional multilevel degenerative changes as detailed above. 3. There is focal marrow signal abnormality involving the residual L1 vertebral body which may represent treated tumor. Osseous defect involving the partially imaged right iliac bone may be related to prior myelomatous lesion or postoperative. There are otherwise no suspicious osseous lesions evident.
