  • Note:—MRA indicates MR angiography; DSA, digital subtraction angiography; M, male; F, female; L, left; R, right.

  • * The fistula was located at T7 left, supplied by the segmental arteries T6 and T7.

  • ** Epidural spinal arteriovenous fistula.

  • *** Tentorial dural arteriovenous fistula. The fistula was located outside the FOV, but the venous drainage was clearly depicted with MRA.
