Central neurocytoma: Report of a rare case and literature review


Central neurocytoma (CN) is an uncommon brain tumor arising primarily in the lateral ventricular near the foramen of Monro and approximately accounting for 0.1-0.5% of all primary tumors of the central nervous system. We report a case of neurocytoma located in the fourth ventricle and extended into the third ventricle. The tumor is composed of uniform round cells with immunohistochemical features of neuronal differentiation. CN is probably a differential diagnosis with oligodendrogliomas and ependymoma. Morphology and immunohistochemical findings associated with clinical and radiological characteristics may support CN diagnosis.
