ABSTRACT

Bilateral sudden sensorineural hearing loss (SNHL) is rare, but a possible symptom of vertebrobasilar ischemia. A 69-year-old woman with hypertension and atrial fibrillation presented with bilateral sudden hearing loss and vertigo without other neurological symptoms. On examination, she had left-beating horizontal nystagmus with positive head impulse on the left side. Pure tone audiometry revealed severe SNHL on both sides. Brain computed tomography angiography (CT angiography) showed a dissection in the proximal portion of the basilar artery (BA) with occlusion of the mid-BA and bilateral anterior inferior cerebellar arteries (AICA), which confirmed on transfemoral cerebral angiography(TFCA). Left common carotid angiography demonstrated retrograde blood flow into the BA and right AICA via the left posterior communicating artery. During TFCA, her right hearing loss dramatically improved. Nine days later, follow-up TFCA showed an improvement of antegrade flow of the BA and AICA. We suggest that vertebrobasilar ischemia can be suspected in patients with bilateral sudden SNHL who present with risk factors for stroke.
