Abstract
Central neurocytomas are rare primary tumors of the central nervous system, most commonly arising in the lateral ventricles. We report the case of a 34-year-old woman diagnosed with a central neurocytoma located in the third ventricle, an uncommon site.
The patient underwent surgical resection via a transcallosal-transchoroidal approach, with intraoperative placement of an external ventricular drain. Gross total resection was achieved. Despite the development of postoperative hydrocephalus, the patient had a favorable clinical outcome and was discharged with preserved functional status.
Histopathological and immunohistochemical analyses confirmed a World Health Organization (WHO) grade II central neurocytoma. Given the extent of resection and tumor characteristics, no adjuvant therapy was indicated. This case highlights the feasibility of complete surgical resection in atypical locations and underscores the importance of perioperative management in optimizing outcomes.
