Introductory chapters discuss history, radiobiology, and neuropathology of radiosurgery, followed by procedures for diseases such as arteriovenous malformations and fistulas, cavernomas, meningiomas, pituitary adenomas, trigeminal neuralgia, vestibular and nonvestibular schwannomas, movement disorders, epilepsy, ocular disorders, pediatric brain tumors, and brain metastases.
In the posterior fossa, stereotactic irradiation is primarily used for the treatment of vestibular schwannomas or meningiomas using dosimetry designed to avoid cranial nerve morbidity, particularly to the facial nerve, while providing adequate dosing to control tumor growth.
The most common primary brain tumors are gliomas, meningiomas, pituitary adenomas, vestibular schwannomas, and primitive neuroectodermal tumors (medulloblastomas).
