Third ventricle, cerebral aqueduct, and fourth ventricle mixed ependymal neurocytoma: a case report and review of the literature

Childs Nerv Syst. 2013 Jul;29(7):1203-6. doi: 10.1007/s00381-013-2064-1. Epub 2013 Mar 12.


Purpose: 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.

Keywords: Central neurocytoma; Cerebral aqueduct; Fourth ventricle; Posterior third ventricle.
