The acute onset of vertigo is a common clinical complaint presenting to physicians. Usually the underlying disease process is benign and self-limited in nature. In the absence of hearing loss or additional neurologic findings, common initial diagnosis is vestibular neuritis, but it must be ruled out from various diseases of the peripheral vestibular disorder. Vestibular neuritis is the name applied by Dix and Hallpike in 1952 to a clinical entity characterized by sudden severe vertigo without deafness, tinnitus, or neurologic symptoms. Caloric tests show unilateral or bilateral weakness. The symptoms gradually disappear, but on some patients dizzy spells reappear in the future. We recently experienced 12 cases of vestibular neuritis and retrospective study of clinical aspects was performed.
