ABSTRACT

Stereotaxic biopsy is an useful technique as an alternative to craniotomy for the tissue diagnosis of the intracranial tumors, especially such as deep seated tumor or malignant neoplasm in the dominant hemisphere. Such biopsy was more safe and lesser expensive than any other procedures and had high accuracy. For the purpose of more accuracy, the authors inserted small steel ball marker at the biopsy site and performed repeat C-T brain scanning immediately after the operation. We could confirm the marker in the tumor tissue on the C-T scans. The authors had experienced 4 cases of stereotaxic biopsy as follow; 2 cases of thalamic astrocytomas, 1 case of pineocytoma and 1 case of astrocytoma grade II in the dominant hemisphere. Neither mortality nor morbidity was noted.
