Two Cases of Central Origin Vertigo Mimicking Acute Vestibular Neuritis / 대한평형의학회지

ABSTRACT

Vestibular neuritis (VN) is characterized by the acute onset of vertigo, nausea and vomiting, in the absence of hearing loss or tinnitus. Cerebellar and brain stem infarction represents approximately 2.3% of acute strokes overall. Those can result from occlusion of the superior cerebellar artery, anterior inferior cerebellar artery, or the posterior inferior cerebellar artery. Central vertigo such as cerebellar or brain stem infarction may present with nonspecific symptoms similar to those of VN. Patients with isolated vertigo due to cerebral infarction may pose a significant diagnostic challenge to the neurotologists. It is know n for being frequently misdiagnosed, often with consequent disability. We report 2 cases of cerebral infarction mimicking VN initially with a review of the related literatures.
