Anterior Inferior Cerebellar Artery Territory Infarct as Cause of Peripheral Vertigo

Abstract

Acute infarcts of anterior inferior cerebellar artery (AICA) are unusual. At the time of the infarction, vertigo, unilateral hearing loss, ataxia, facial numbness and palsy are symptoms frequently observed. However, transient ischemia of the inner ear and vestibular nerve prior to the infarction may result in isolated peripheral vertigo in subjects with risk factors of hypertension and/or diabetes. In this study an AICA infarction case with peripheral vertigo that is resistant to medical management is presented. Like this case we mentioned, in patients with medically resistant peripheral vertigo and whom carry those risk factors, an infarct of AICA should be considered and further investigations such as an MRI should be performed.
