Sudden bilateral hearing loss due to vertebral artery dissection

Abstract

AbstractA 69‐year‐old man suddenly developed bilateral hearing impairment and dizziness. Magnetic resonance imaging showed multiple infarctions in the area of the bilateral posterior circulation, and magnetic resonance angiography showed a completely occluded right vertebral artery (VA) and severe stenosis of the left VA. Pearl and string sign was detected in the left VA by cerebral angiography, leading to the diagnosis of arterial dissection. The infarctions in the anterior inferior cerebellar artery area were considered a result of artery‐to‐artery embolism. He regained his hearing gradually and was discharged in 2 weeks. Acute ischemic stroke with bilateral hearing loss is generally accompanied by proximal severe vascular legions, with poor outcome. Prognosis may depend on the underlying vascular pathology.
