Although sudden deafness occurs with anterior inferior cerebellar artery infarction, the deafness is usually associated with other brainstem or cerebellum sign such as crossed sensory loss, lateral gaze palsy, facial weakness, Horner syndrome or limb dysmetria. An 84-year-old woman suddenly developed right-sided tinnitus, hearing loss, vertigo, and vomiting. Audiometry and electronystagmography documented absent auditory and vestibular functions on the right side. T2-weighted and diffusion-weighted MRI showed a tiny infarct in the right lateral inferior pontine tegmentum. Anterior inferior cerebellar artery occlusion can cause sudden deafness and vertigo without brainstem or cerebellar signs.
