Abstract
- Vestibular neuritis represents as a spinning type of dizziness accompanied by nausea, vomiting. Central vertigo such as cerebellar infarction may present with nonspecific symptoms similar to those of vestibular neuritis. Basilar artery supplies the cerebellum by branching out into superior cerebellar artery, anterior inferior cerebellar artery, and posterior inferior cerebellar artery. The patient had spinning type of vertigo, nausea, vomiting on the day of visit without any otologic symptoms. Only spontaneous nystagmus was observed. After admission, the patient's dizziness aggravated and emergency brain magnetic resonance imaging was performed. As a result, infarction in the posterior inferior cerebellar artery area was observed. Anticoagulant therapy was performed. Dizziness decreased, the follow-up imaging study showed improvement of the infarction, and the patient was discharged. We experienced three cases of PICA infarction presenting as peripheral types of dizziness, and therefore we are reporting the case.
