Stereotactic Radiosurgery for the Management of Brain Metastases

A 50-year-old man with a history of lung cancer presents with headaches and right-arm numbness; he is found to have a single brain metastasis. Stereotactic radiosurgery is recommended as part of his care. Stereotactic radiosurgery uses multiple narrowly focused beams of radiation to treat one or a few focal lesions while minimizing effects on the surrounding tissue.
