  • Abstract
  • Look Inside

A 76-year-old male presented with a 30-years' history of a mass in the right tonsillar area. CTand MRI showed a large encapsulated mass occupied in the right parapharyngeal space ex-tending to the skull base. Angiography demon-strated a nonvascular mass displacing both the internal and external carotid arteries laterally. The patient underwent surgery under general anesthesia. After tracheostomy, the mass was extirpated through a lateral neck incision. Histo-pathological examination of the mass with HE, EVG and PTAH stains demonstrated an aneurysm.
