Gangliogliomas in children. A clinicopathological study.

14 children with central nervous system gangliogliomas are reviewed. The tumors were most frequently located in the cerebral hemisphere and often were cystic and calcified. Total removal was performed in only 1 patient. A well-defined plane of cleavage could not obtained in the majority of tumors at surgery. All patients are alive on follow-up and only 1 is neurologically disabled. Radiation therapy was given to 4 patients postoperatively. The clinical course of patients given postoperative radiation therapy was not different from that of those who were not irradiated. The histological aspects of the tumors are described.
