Brachytherapy delivers high doses of radiation to brain tumors while sparing normal surrounding tissue. It may be used as a primary treatment, an adjuvant treatment, or as therapy for recurrence of some malignant gliomas, low-grade astrocytomas, meningiomas, metastases, and pediatric brain tumors. ⋯ Although radiosurgery is supplanting brachytherapy for many indications, brachytherapy remains a viable option. This article discusses the radiobiology, procedures, clinical applications, and outcomes of brachytherapy in managing brain tumors.
