A case of cerebello-pontine angle infarction found by vertebral angiography.

A patient was admitted complaining of sudden vertigo. Otoneurological examinations, electronystagmography (ENG), and vertebral angiography (VAG) showed constriction of vertebral artery and anterior inferior cerebellar artery, and basilar artery obstruction. Based on these findings, we diagnosed the case as posterior cranial fossa infarction. Computed tomography (CT) and magnetic resonance imaging (MRI) findings were negative. The authors conclude that VAG should be performed in certain cases of vertigo thought to be of central nervous origin when CT and MRI findings are both negative.
