title: Endoscopic assisted excision of a retroclival arachnoid cyst presenting as hysterical breathlessness.
abstract: BACKGROUND
  Arachnoid cysts are benign developmental cysts occurring most commonly in the middle fossa. Posterior fossa arachnoid cysts are less common, with retroclival arachnoid cysts especially in the pediatric age group being rare.
  
  
  METHODS
  We present a case of a retroclival interpeduncular farachnoid cyst in a 10-year-old boy who presented with left-sided ptosis and episodes of hysterical breathlessness.
  
  
  RESULTS
  The surgical treatment involved endoscopic assisted microsurgical excision of the cyst and the child made an uneventful and complete recovery with complete cessation of breathlessness. The clinical presentation, etiopathogenesis, imaging characteristics and treatment modalities are discussed and the relevant literature reviewed.
