title: Brainstem hemorrhage presented as audiovestibular syndromes.
abstract: Brainstem hemorrhage usually presented with acute multiple neurologic dysfunction, and the prognosis was poor. Rarely, it can manifest with audiovestibular symptoms only. Here, we report a case of brainstem hemorrhage involving the right middle cerebellar peduncle and dorsal lateral pons presented with constant nonpulsatile tinnitus and rotatory vertigo. We believed that rotatory nystagmus should be regarded as a central sign until proven otherwise even if the neurologic signs are subtle.
