title: Giant Vertebrobasilar Fusiform Aneurysm as a Cerebellopontine Angle Mass.
abstract: BACKGROUND
  According to the literature, a fusiform aneurysm located in the cerebellopontine angle (CPA) is an extremely rare condition.
  
  
  METHODS
  We report a case of a 59-year-old patient with initial dizziness and left-sided sensorineural hearing loss that had gradually developed over six months. Vertebrobasilar fusiform aneurysm, with intraluminal thrombus, which was displaced to the right cerebellopontine angle, creating mass effect, was diagnosed using brain magnetic resonance imaging and magnetic resonance angiography.
  
  
  CONCLUSIONS
  Atherosclerosis may be the essential factor in the pathogenesis of a fusiform aneurysm of the basilar artery, especially in elderly patients. The best treatment option is yet to be determined, but in soite of numerous previous large studies, personalized approach is probably the best.
