A case of cerebellar arteriovenous malformation presented with vertigo, hearing loss, and headache

Abstract

We report a 48-year-old man presented with episodic rotatory vertigo accompanied by right hearing loss and headache. He did not have medical history of migraine. His hearing loss was progressive. He showed unilateral (right-sided) absence of cervical and ocular vestibular evoked myogenic potentials (cVEMP and oVEMP) to the right ear stimulation, while his caloric tests were normal on both sides. His signs and symptoms were suggestive of right peripheral vestibular vertigo except for headache. MRI revealed cerebellar arteriovenous malformation (AVM). Headache might be a sole cue for correct diagnosis. On the diagnosis of vertigo patients with headache, vertigo associated with secondary headache must be considered.
