Acute vestibular syndrome (AVS) is characterized by the rapid onset of dizziness/ vertigo accompanied by nausea/vomiting, gait unsteadiness, and nystagmus lasting a day or more. Some patients with AVS have potentially dangerous central etiologies. AVS caused by central etiologies without significant other neurologic deficit, so called pseudo-vestibular neuritis (pseudo-VN), could be difficult to be differentiated from acute vestibular neuritis. In addition to imaging studies, bedside oculomotor examination-head impulse test, nystagmus and test of skew)-is essential to identify patients with pseudo-VN. Among several central causes of AVS, brain tumor is extremely rare. We report a case of vascular tumor involving the anterior inferior cerebellum with AVS presentations.
