Chapter 22: Stereotactic Treatments

Stereotactic radiosurgery (SRS) is typically a single treatment delivering a high dose to a target in the brain. It is used to treat a variety of conditions, including metastatic cancer lesions, acoustic neuromas, meningiomas, arteriovenous malformations trigeminal neuralgia, and (less commonly) functional disorders such as obsessive–compulsive disorder or essential tremors. It is beyond the scope of this text to discuss the clinical aspects of these conditions in detail, but they span the range from highly aggressive cancers to slow-growing tumors and benign conditions.
