title: Neuroendoscopic aspiration of tumors in the posterior third ventricle and aqueduct lumen: a technical update.
abstract: BACKGROUND
  Small soft ventricular tumors are good candidates for complete removal by a purely endoscopic technique. This approach is particularly interesting for lesions located in the posterior third ventricle and aqueductal lumen.
  
  
  METHODS
  We present our method of endoscospic aspiration through direct contact between the tumor and the working channel of a flexible scope.
  
  
  RESULTS
  Aspiration without the intermediate use of cannulas is safe and has proved to be effective in the apparently total or partial removal of three soft tumors of different pathologies located in the third ventricle or aqueductal lumen. In one case, a second neuroendoscopy a few months later to repeat endoscopic third ventriculostomy (ETV) offered a unique opportunity to observe the absence of the tumor and the restored anatomy.
  
  
  CONCLUSIONS
  Neuroendoscopy provides a safe, effective way to radically resect small soft tumors in these troublesome locations and can be a valuable alternative to microsurgery.
