MR [[spectroscopy]] (MRS) can be useful in characterizing [[intraventricular tumor]] and distinguishing CNCs from meningiomas and other intraventricular tumors

**In adults, and depending on location, consider**:

[[Choroid plexus papilloma]], [[metastasis]],  [[cysticercosis]].


[[Intraventricular ependymoma]]

[[Intraventricular meningioma]]

[[Subependymoma ]] 

[[Central neurocytoma]]

exophytic glioma

[[Papillary ependymoma]] is a rare variant of ependymoma and often gives rise to confusion with [[choroid plexus papilloma]] because of topographic, light microscopic and ultrastructural similarities.
