Neurocytoma
Pronunciation: NEW-roh-sy-TOH-mah
A rare, typically benign intraventricular brain tumor composed of neuronal and glial elements.
Full Definition
Neurocytoma is a rare intraventricular brain tumor that most commonly arises in the lateral ventricles near the foramen of Monro. These tumors are composed of mature neuronal cells with glial elements and typically present in young adults. In medical documentation, central neurocytomas are distinguished from extraventricular neurocytomas, which may have different biological behavior. The term carries prognostic implications as these tumors generally have favorable outcomes following surgical resection. Editors should note that while traditionally considered benign, atypical neurocytomas may exhibit more aggressive features.
Usage
Usage note: Central neurocytomas are specifically intraventricular; extraventricular variants may behave differently.
