Systemic staging of supratentorial extra-axial brain tumors in children. Craniopharyngiomas, atypical teratoma and teratoid tumors of the suprasellar region (germinomas), and intracranial teratomas.

A staging system has been proposed for the following tumors: craniopharyngiomas, germinomas, and intracranial teratomas. Various aspects of the specific pathologic and growth characteristics of the tumor determines such categorization and subclassification of the tumors. A brief analysis of the clinical aspects in reference to classification is presented. The suggested systems will need to be tested in clinical studies to determine their validity.
