She was discovered to have a big right-sided tentorial arteriovenous fistula (AVF) with enlarged deep draining veins, together with the vein of Rosenthal. The affected person underwent Onyx embolization of the fistula through a mixed transarterial and transvenous strategy leading to full obliteration of the fistula.
