Central neurocytomas of the posterior third ventricle are rare. These typically benign
lesions have recently been shown to respond well to Gamma knife stereotactic radiosurgery
(SRS). We present the case of a posterior third ventricle central neurocytoma presenting
with aqueduct obstruction. The patient was treated with endoscopic biopsy and endoscopic
third ventriculostomy, followed by Gamma knife radiosurgery. At 2 years the tumor
has diminished in size and the patient is neurologically intact. This treatment strategy
may avoid the risk of open ventricular surgery and the need for shunts in patients
with central neurocytomas of appropriate size and location.
