Multimodality stereotactic techniques were used in the management of 3
9 patients with craniopharyngiomas in a 12-year interval. Monocystic c
raniopharyngiomas were treated successfully by intracavitary beta-irra
diation using P-32 (96% cyst control rate). Solid tumor progression or
secondary cyst formation required repeat irradiation, radiosurgery or
microsurgery in selected patients. In the future, wider and earlier a
pplication of stereotactic techniques may further reduce the still una
cceptable morbidity currently associated with initial radical microsur
gical resection of craniopharyngiomas.
