FIG 3. A, Anteroposterior subtracted view of early arterial-phase injection of the left hypogastric artery shows dural AVF (arrow) with sacral feeding vessels. Arrowheads signify draining veins.
B, Sagittal contrast-enhanced T1-weighted (400/14) MR image shows intraparenchymal cord enhancement as well as enhancement of enlarged vessels on the cord surface.
C, Sagittal FSE T2-weighted (4400/100eff) image shows multiple flow voids on the cord surface, increased signal intensity within the central cord, as well as a rim of peripheral hypointensity (arrowheads).
