Sudden sensorineural hearing loss is a clinical condition characterized by a sudden onset of unilateral or bilateral hearing loss. In recent years sudden deafness has been frequently described in association with anterior inferior cerebellar artery (AICA) infarction generally presenting alongwith other brainstem and cerebellar signs such as ataxia, dysmetria and peripheral facial palsy. The authors report a rare clinical case of a 53-year-old man who suddenly developed hearing loss and tinnitus without any brainstem or cerebellar signs. Computed tomography of his brain was normal, and the audiological results localized the lesion causing deafness to the inner ear. Surprisingly, magnetic resonance imagingshowed an ischemic infarct in the right AICA territory. This case represents the fifth in the literature to date but it confirmsthat AICA occlusion can cause sudden deafness even without brainstem or cerebellar signs. Therefore, we recommendsubmitting the patient for neuroimaging, as an emergency, in order to exclude infarction of the AICA territory. By doing this, it may be possible to limit the extent of the lesionby commencing early therapy.
