Intraventricular Metastases ¹⁾.

MR spectroscopy (MRS) can be useful in characterizing intraventricular tumor and distinguishing CNCs from meningiomas and other intraventricular tumors ²⁾.

Intraventricular Vascular Lesion ³⁾

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.
