title: Paired Colloid Cysts in the Third Ventricle.
abstract: BACKGROUND
  Colloid cyst is the most common neoplastic lesion of the third ventricle, and the occurrence of 2 colloid cysts in the ventricular system is rare.
  
  
  METHODS
  We present a 35 year old female patient with paired colloid cysts of the third ventricle who presented with obstructive hydrocephalus and were treated surgically with the transcallosal interhemispheric transforaminal approach. Until now only 3 patients of dual or paired colloid cysts of different ventricles were reported. To the best of our knowledge, this is the first case with both the colloid cysts present in the third ventricle.
  
  
  CONCLUSIONS
  This report illustrates the importance of proper radiologic study in a case of colloid cyst and preparing preoperatively and excision of both the colloid cyst whenever present, ​to prevent the recurrence.
