Overview

Central neurocytoma is a rare brain tumor predominantly encountered among young patients typically localized close to the foramen of Monro and septum pellucidum. In the absence of atypical histology, the prognosis after complete resection is usually excellent. We present a case of a 30 years old man with mild hemiparesis which led to the diagnosis of a tumor of the third and both lateral ventricles. The patient underwent partial tumor resection in two surgeries. Histologically the tumor resembled oligodendroglioma, however the cells were imunoreactive for synaptophysin. MIB-1 proliferative index was higher than 3%. On the basis of these findings, diagnosis of atypical central neurocytoma was made. The patient is symptom-free 18 months after the first surgery, residual tumor is closely observed. At the first sign of progression the patient will recieve radiotherapy. Apart from the case report we review the literature and discuss clinical and therapeutical aspects of this tumor.

Key words:
brain neoplasm – neurocytoma – intraventricular tumor – radiation therapy – synaptophysin
