전정신경염으로 오인된 후하소뇌동맥 경색 2예

Vestibular neuritis is characterized by the acute onset of spinning type of dizziness, nausea and vomiting, in the absence of hearing impairment and tinnitus. Central vertigo such as cerebellar infarction may present with nonspecific symptoms similar to those of peripheral vestibulopathy. It is known for being frequently misdiagnosed, therefore cerebellar infarction may pose a significant diagnostic challenge. Basilar artery supplies the cerebellum by branching out into superior cerebellar artery (SCA), anterior inferior cerebellar artery (AICA), and posterior inferior cerebellar artery (PICA). We experienced two cases of PICA infarction presenting as vestibular neuritis types of dizziness, and therefore we are reporting the cases. (J Clinical Otolaryngol 2012;23:101–104)
