title: Neurenteric cyst of the cerebellopontine angle: case report.
abstract: OBJECTIVE
  We report a case of a neurenteric cyst of the cerebellopontine angle and review the five previously reported cases. The pathology and classification of these cysts are discussed.
  
  
  METHODS
  The patient presented with a 1-month history of nausea, vomiting, vertigo, and sudden hearing loss.
  
  
  METHODS
  The cyst was decompressed by a retrosigmoid approach. After recurrence of symptoms at 2 months, further decompression was required.
  
  
  CONCLUSIONS
  The patient achieved a good outcome after the second operation, with cessation of her vomiting and vertigo, although she had residual hearing loss. Four of the five previously reported patients experienced satisfactory outcomes after surgery. The definitive diagnosis of these rare lesions is made using immunocytochemical techniques.
