Recurrent Central Neurocytoma Treated with Robotic Radiosurgery

Abstract

Central Neurocytoma is a rare intraventricular neuroepithelial tumor (<1% of primary brain tumors). Surgical resection is the standard treatment, however 30-50% of cases result in subtotal resections. Due to its rare incidence, the therapeutic approach to disease persistence or local recurrence after surgery remains controversial. Recurrence of these tumors can be associated with intracranial bleeding, malignant transformation, or meningeal dissemination, making their local control a challenge. With the advance of radiotherapy techniques, it is estimated that it may play a significant role in the treatment of these tumors. We describe a case report of recurrent Central Neurocytoma effectively and safely treated with Cyberknife® Robotic Radiosurgery. After a follow-up of 81 months, the patient remains asymptomatic without signs of disease progression.
