The septum pellucidum is displaced towards the left. The central neurocytoma arises from neuronal precursor elements rather than from glial cells. It usually appears as a well-defined, lobulated intraventricular mass growing near the foramen of Monro or septum pellucidum. Enhancement is typically mild to moderate and calcifications and cystic changes are common.
Most patients are young adults and can present with symptoms of ventricular obstruction.
Uncommonly, there have been cases of more aggressive tumor with dissemination. Schild, SE et al. Central neurocytoma with clinically malignant behavior.
