Use of gamma knife radiosurgery for intracranial tumors

Abstract

Gamma knife radiosurgery of intracranial tumors is a noninvasive treatment with zero mortality and low and acute late morbidity. While microsurgery prevents growth of the tumor in the case of radical resection, radiosurgery prevents its growth, although the tumor is left in place. Contrary to microsurgery, the result of treatment using radiosurgery is not empty space in place of the tumor. In follow-up images, the tumor remains in place, but does not increase in volume. Eventually, regression of the tumor can be observed. Due to its epidemiology and incidence in the population, the most frequent tumor indications that lend themselves to gamma knife radiosurgery are meningiomas, acoustic neurinomas, pituitary adenomas and brain metastases.
