Intraventricular tumors of childhood

Supratentorial intraventricular tumors in childhood are relatively uncommon neoplasms. They are generally benign lesions with certain anatomic predilection, producing symptoms by local expansion and obstruction of cerebrospinal fluid flow. Increased intracranial pressure occurs without focal neurologic deficit because of their relatively silent central cerebral location. The benign nature of supratentorial intraventricular tumors preclude a formal staging system. Listing of tumor type and anatomic location is sufficient.
