Abstract

The authors present their experience with stereotactic biopsy of brain tumors. Biopsies were obtained sequentially at different depths from the center of the tumor according to coordinates derived from computerized tomography (CT). Biopsies were obtained from 23 brain tumors: 17 gliomas, 5 metastases, and 1 lymphoma. In all a total of 137 biopsies were studied from both enhancing and nonenhancing areas. The tumor yield from these biopsies was 68 and 73%, respectively. It appears that tumor tissue may be obtained from both the enhancing periphery as well as the nonenhancing center of tumors.
