On day 3, an extremely small lesion with high-intensity signal was detected in the dorsal part of the middle medulla on 3-tesla DW MRI with a section thickness of 2 mm (Fig. 1).
a A cold-air (12 C) caloric test showed left canal paresis (40%). mPSV, maximum slow phase velocity; Rt, right; Lt, left. b Ocular vestibular-evoked myogenic potentials elicited by vibratory stimuli at the forehead showed a 64% decline in amplitude when recorded below the right eye. c Video-oculography recording showed visual suppression during the light phase (53%).

Ocular vestibular-evoked myogenic potentials (VEMPs) elicited by vibratory stimuli at the forehead showed a 64% decline in amplitude when recorded below the right eye (Fig. 2), whereas no significant differences were observed for cervical VEMPs.
