title: [Extracranial internal carotid artery aneurysm].
abstract: BACKGROUND
  Extracranial aneurysm of the internal carotid artery is an exceptional finding.
  
  
  METHODS
  An 89-year-old woman consulted for a peritonsillar mass. Physical examination revealed a parapharyngeal pulsatile mass in the oropharynx. Computed tomography (CT) provided the diagnosis of extracranial internal carotid artery aneurysm. Endovascular or surgical treatment were declined. Anticoagulation medication was given.
  
  
  CONCLUSIONS
  We reviewed the CT and magnetic resonance imaging findings and the clinical manifestations of extracranial internal artery aneurysm. Endovascular treatment is an alternative to open surgery.
