title: Third ventricle, cerebral aqueduct, and fourth ventricle mixed ependymal neurocytoma: a case report and review of the literature.
abstract: OBJECTIVE
  A case report of an 8-year-old female who underwent interhemispheric transcallosal approach to the third ventricle, cerebral aqueduct, and fourth ventricle for resection of a mixed ependymal neurocytoma and review of the literature was evaluated.
  
  
  METHODS
  An Ovid MEDLINE review of the literature was conducted starting in 1946 to current using search terms as described in our keywords.
  
  
  RESULTS
  A total of 16 neurocytoma have been described in the literature as either posterior third ventricle or posterior fossa in origin. Of these lesions, five have been described as mixed glial-neuronal and all of these were located in the fourth ventricle. To our knowledge, this is the first described mixed glial-neuronal tumor located in the posterior third ventricle and aqueduct.
