Stereotactic localization (with computerized tomographic scanning), biopsy, and radiofrequency treatment of deep...

In eight patients stereotactic biopsy of deep brain lesions was performed. Adequate tissue was obtained, and the information helped considerably in planning further therapy. No significant complications occurred in these patients. In three of the cases, the stereotactic coordinates were determined from the computerized tomographic (CT) scan. In one patient, after biopsy, stereotactic radiofrequency (RF) lesions in the tumor resulted in temporary improvement.
