====== 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.
