Late neoplastic complications after radiation treatments for benign intracranial tumors.

There is increasing interest in the use of radiation treatment as an adjunct or an alternative to microsurgery in the management of a range of intracranial tumors. Most of these treatments are performed with linear accelerator or Gamma Knife systems. Precise targeting with stereotactic localization minimizes the volume of tissue being irradiated for single and multiple fraction irradiation. The incidence of secondary neoplasms after radiosurgery may be significantly less than that reported after whole-brain or two- or three-field radiotherapy.
