We report a juvenile patient presenting with recurrent ischemic stroke caused by BHS, which was revealed by carotid duplex ultrasonography. Carotid duplex ultrasonography performed in the neutral position showed normal findings. However, disappearance of end-diastolic blood flow of contralateral VAs was observed with head rotation. Digital subtraction angiography confirmed occlusion at C1/2 levels in the VA contralateral to the head rotation, bilaterally. Importantly, our patient did not recognize the association of head rotation and previous episodes of stroke. We suggest that BHS should be considered in patients with cryptogenic stroke occurring in the vertebrobasilar artery territory.
