초록
Rotational vertebral artery syndrome (RVAS), also called Bow-Hunter syndrome, is characterizedby position-aggravated reversible vertebra-basillarischemia. By rotating the head toone side, the mechanical compression of a dominant vertebral artery (VA) in the setting of ahypoplastic contralateral VA might cause tinnitus, vertigo and syncope. A 60-year-old maleexperienced recurrent tinnitus and vertigo while rotating the head to the right side. Neck CTimages showed no abnormal structures near the course of both VAs. In 3-phase dynamic neckCT angiography, a focal vertebral artery dissection was identified at the right C6 transverseforamen. Close observation and anticoagulation therapy were started to prevent thrombo-emboliccomplications. Herein, we report a case of RVAS with vertebral artery dissection with areview of the literatures.
