====== Central Neurocytoma Differential Diagnosis ====== [[Ependymoma]] more frequent in childhood more commonly in 4th ventricle supratentorial tumors (esp in children) often have a significant extraventricular (parenchymal) component [[intraventricular meningioma]] homogeneous contrast enhancement well-circumscribed mass [[subependymoma]] typically found in the 4th ventricle usually older individuals may have ependymoma components and look very similar [[subependymal giant cell astrocytoma]] (SGCA) in patients with [[tuberous sclerosis]] vivid contrast enhancement [[choroid plexus papilloma]] (CPP) mainly in children typically show intense contrast enhancement intraventricular metastases older patients usually stronger contrast enhancement history of primary (e.g. RCC) [[oligodendroglioma]] this is especially difficult in cases where there is a parenchymal component as histologically the tumours are very similar.
