Sagittal spine MR T2-weighted image demonstrated flow voids at perimedullary spaces (A, arrows). Axial views at the level of right L1/L2 intervertebral foramen revealed the spinal dural arteriovenous fistula (SDAVF) arose around a circumscribed tumor which was heterogeneously hyperintense on T2-weighted images (B, arrowhead) and diffusely enhanced on post-contrast T1-weighted images (C, arrowhead)
