title: Angioleiomyoma of the internal auditory canal: clinical and radiographic features.
abstract: OBJECTIVE
  Discussion of a rare case of angioleiomyoma of the internal auditory canal.
  
  
  METHODS
  Thirteen-year-old female patient with a 1-year history of progressive hearing loss.
  
  
  METHODS
  Middle cranial fossa approach providing complete surgical extirpation.
  
  
  METHODS
  Surgical pathology.
  
  
  RESULTS
  Radiography and history suggestive of vestibular schwannoma; pathology revealed angioleiomyoma.
  
  
  CONCLUSIONS
  Angioleiomyoma is a rare lesion of the internal auditory canal that has many similar clinical and radiographic features of a vestibular schwannoma. There are no previous reports of this tumor occurring within the internal auditory canal in this age group.
