Figure 2: Preoperative and postoperative images of patient 1: (a) Preoperative magnetic resonance angiography showing tumor blush (arrow). (b) Magnetic resonance venography showing total obliteration of sigmoid sinus and proximal half of internal jugular vein (arrow head). (c) Preembolization digital subtraction angiography showing tumor being fed from ascending pharyngeal artery (star). (d) Postembolization digital subtraction angiography showing no tumor blush. (e) Postoperative computed tomography showing near-total petrosectomy (asterisk) with total excision of the lesion
