Central neurocytomas are WHO grade II neuroepithelial intraventricular tumors with fairly characteristic imaging features, appearing as heterogeneous masses of variable size and enhancement within the lateral ventricle, typically attached to the septum pellucidum. Although structural imaging findings of CNC are typical, they are not specific. Immunohistochemistry confirms the purely neuronal origin by positivity to neuronal markers such as 11: Importantly, IDH mutations and 1p19q co-deletion are absent (characteristic of oligodendrogliomas). The cells are typically uniform and round with a salt and pepper finely speckled chromatin 11. Objectives: Typically, central neurocytomas present with symptoms of increased intracranial pressure, headaches being most frequent, or seizures (especially tumors with extraventricular extension). These lesions may obstruct spinal fluid flow and/or put pressure on surrounding structures, causing symptoms including headaches and confusion. Other differentials for an intraventricular mass including an ependymoma or intraventricular metastasis are felt less likely given the imaging appearances. (2009) Magnetic resonance imaging.
