Rapid, unilateral injury to either peripheral or central vestibularstructures produces the acute vestibular syndrome, which consistsof severe vertigo, nausea and vomiting, spontaneous nystagmus,and postural instability. When this syndrome evolves over daysin a healthy person, it is usually attributed to a viral vestibularneuritis, also called vestibular neuronitis or, when acute hearingloss occurs, neurolabyrinthitis.1,2,3,4,5,6 Infarction and hemorrhageof the inferior cerebellum, however, may simulate vestibularneuritis (Figure 1).9,10 As many as 25 percent of patients withrisk factors for stroke who present to an emergency medicalsetting with isolated, severe vertigo, nystagmus, and postural. . .
