Acute back pain, rule out metastases 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 at the lower limits of normal at the lower L2 level. There is fatty infiltration of the filum terminale measuring 1 to 2 mm in thickness and extending from the mid L4 to the S2 levels. 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: Disc desiccation and minimal bulge. No spinal canal or neural foraminal stenosis.L4-L5: Disc bulge eccentric to the right and small right central disc extrusion with cranial migration. No spinal canal stenosis. Mild right and minimal left neural foraminal narrowing. Mild facet arthropathy.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis. Mild facet arthropathy.Paraspinous soft tissues are within normal limits.
1. No evidence of metastatic disease.2. Mild multilevel degenerative changes including a small disc extrusion at the L4-L5 level. No high-grade spinal canal or neural foraminal stenosis at any level. Mild right L4-L5 neural foraminal stenosis. Additional details as above.3.Fatty infiltration of the filum terminale with borderline low conus at the inferior L2 level. These findings may be incidental but would suggest correlation for signs of spinal cord tethering.
