Abstract

Objective: We report a rare case of an ascending pharyngeal-internal jugular arteriovenous fistula (AP-IJ AVF).
Case presentation: A 32-year-old woman was admitted with a 5-year-history of pulsatile tinnitus. Left external carotid angiography demonstrated a single-hole AVF between the ascending pharyngeal artery and the superior bulb of the internal jugular vein. The fistula was completely occluded by transarterial embolization using detachable coils. The patient showed immediate improvement after embolization.
Conclusion: AP-IJ AVF is considered a subgroup of parachordal AVFs. Transarterial embolization is an effective treatment for this condition.
