FIG 4. Spinal dural AVF at the left T11–T12 neural foramen (case 8).
A and B, Selective DSA (A) and anteroposterior MIP projection of MR angiogram (B) depict the fistula (long arrow) located at the T11–T12 neural foramen. An enlarged medullary vein (short arrow) draining the fistula to the tortuous, dilated posterior median vein (arrowheads) is clearly seen.
C, An axial targeted view from the MR angiographic data shows the location of the fistula (arrow) at the left T11–T12 neural foramen.
