Stereotactic biopsy followed by radiation therapy may be considered in certain circumstances. These include patients with a tumor located in an eloquent area of the brain, patients whose tumors have minimal mass effect, and patients in poor medical condition, precluding general anesthesia. Median survival after stereotactic biopsy and radiation therapy is reported to be from 27-47 weeks. [124]

A study by Jakola et al found that surgical procedures may not significantly alter the quality of life (QOL) in the average patient, however, the use of intraoperative ultrasonography may be associated with a preservation of QOL in that it helps avoid introducing new deficits. [125]
