title: Neuroendoscopic approach to quadrigeminal cistern arachnoid cysts.
abstract: OBJECTIVE
  The introduction of neuroendoscopy has provided a minimally invasive modality for the surgical treatment of quadrigeminal arachnoid cysts. Three pediatric patients with arachnoid cyst of the quadrigeminal cistern treated by endoscopic fenestration are reported.
  
  
  METHODS
  The hospital records of patients were retrospectively rewieved. All patients had hydrocephalus. A lateral ventricle-cystostomy and endoscopic third ventriculostomy were performed by using rigid neuroendoscopes.
  
  
  RESULTS
  There were one boy and two girls with ages 7 months, 9 months and 14 years, respectively. One patient had undergone shunting prior to neuroendoscopic surgery. The postoperative course was uneventful in all cases, with no complications. They showed disappearance of intracranial hypertension symptoms and significant reduction of the cyst size.
  
  
  CONCLUSIONS
  Neuroendoscopic technique is an effective and suitable method for the treatment of quadrigeminal cistern arachnoid cysts and accompanying hydrocephalus.
