Presentation
Left S1 radiculopathy
Patient Data
Normal alignment. Normal lower cord and conus.
T12/L1 to L3/4: No significant abnormality
L4/5: Mild annular disc bulge with mild canal stenosis and no significant focal nerve root compression
L5/S1: A very large central and left-sided disc herniation with extruded fragment occupies 80% of the cross-sectional area of the spinal canal causing severe compression of the left, moderate compression of the right S1 root and severe compression of the lower sacral nerve roots within the thecal sac. L5 roots exit above the disc herniation.
Conclusion:
Very large extruded disc at L5/S1 causing severe sacral nerve root compression.
