1. Fig year-old man with lower legs numbness was diagnosed with severe canal stenosis at L3/4 and L4/5 and moderate canal stenosis at L2/3. A. MR myelography displays engorged and tortuous vein (white arrows) across only about 2 vertebrae along with tangle of flow voids (arrowheads), which are possibly redundant nerves and vessels, just proximal to level of stenosis. These findings are distinguishable from that of Figure 2A. B. Sagittal T2-weighted spinal MR image shows annular bulging at L2/3 to L4/5, causing moderate and severe spinal canal stenosis (white arrows) without spinal cord edema.
