title: Congenital peripheral facial palsy associated with cerebellopontine angle arachnoid cyst.
abstract: OBJECTIVE
  A rare case of cerebellopontine angle arachnoid cyst leading to congenital peripheral facial palsy was presented.
  
  
  METHODS
  A 1-year-old girl presented with peripheral facial paralysis since birth. Computed tomography and magnetic resonance imaging revealed left cerebellopontine angle arachnoid cyst causing moderate displacement of the brain stem.
  
  
  METHODS
  Retrosigmoid suboccipital craniotomy was performed and microsurgical resection of the cyst wall and fenestration of the cyst to the basal cisterns were achieved.
  
  
  CONCLUSIONS
  Cerebellopontine angle arachnoid cyst should be considered as a potential cause of congenital peripheral facial palsy.
