We wished to clarify the possible complications related to this venous variant. We described 2 rare cases of troublesome pulsatile tinnitus associated with prominent vein of hypoglossal canal, which communicates with the jugular bulb and the marginal sinus. Both cases were successfully treated by positioning a stent across the vein of hypoglossal canal and jugular bulb. The 2 present clinical cases represent the first report of such a condition. The therapeutic decision-making is discussed in relation to the persistent pulsatile tinnitus and the etiopathologic hypothesis put forward.
