The authors reports on a case of pulsatile tinnitus, where otoscopy revealed a retrotympanic mass. The initial tympanic diagnosis was confirmed by a CT-scan. However, surgical exploration revealed a large artery situated on the promontory. Post-operatory arteriography confirmed that this artery in the tympanic cavity was in fact the internal carotid artery.
