A 58-year-old man presented with sudden onset left-sided sensorineural hearing loss in 2011. The patient had pre-existing arterial hypertension. Brain magnetic resonance imaging (MRI) with angiographic sequences demonstrated vertebral and basilar megadolichoectasia with aneurysmal dilatation of the intracranial portions of the vertebral arteries [Figure 1]. A floating thrombus of the left vertebral artery probably led to the internal auditory artery occlusion without vertebrobasilar infarction. He never regained his hearing. Assessment for Fabry disease did not reveal any abnormality. The follow-up magnetic resonance angiography showed aggravation of these vascular abnormalities causing progressive extra-axial cranial nerve compression [Figure 2]. The patient developed swallowing dysfunction and dysarthria, but with no evidence of stroke despite the presence of the partially thrombosed left vertebral artery aneurysm. The swallowing dysfunction led to respiratory distress and the patient required admission to an intensive care unit. Percutaneous endoscopic gastrostomy and tracheostomy were performed and then he was directed to a rehabilitation center.{Figure 1}{Figure 2}

Endovascular intervention had been considered but was not performed since the arterial dilatation was too long to be treated, and stenting would have resulted in a significant risk of vertebrobasilar ischemia [Figure 3]. Megadolichovertebral and basilar arteriopathy are generally attributable to arterial hypertension. Surgery for microvascular decompression or endovascular treatment of the aneurysm have been proposed, but literature on this subject is sparse and consists only of a few case reports.[1]{Figure 3}
