[Pathological aspects of the tumors of the lateral ventricles].

Typing a tumor of the lateral ventricle is often an issue, even for an experienced Neuropathologist. In this location are encountered specific entities, such as neurocytoma and subependymal giant cell astrocytoma, as well as more usual tumors, displaying a common misleading morphology, for instance a main clear cell component. The panel of diagnostic tools given to the pathologists has been increasing for a few years, enriched by immunohistochemical and molecular probes.
