Abstract
- CT guided stereotactic biopsies were carried out in 41 patients with tumorous CT findings during past 2 years. In 27 tumorous CT conditions impressed glioma, meningioma, metastatic ca, chondroma, germinoma and craniopharyngioma, 16 cases were disclosed correctly in preoperative cinicalradiological diagnosis comparing with pathological diagnosis confirmed by means of stereotactic biopsy, but other 11 cases, showed the preoperative diagnostic error which pathological diagnosis were infarction, cryptical AVM, abscess, granuloma, and tumors such ad lymphoma, oligodendroglioma, GBM, chordoma. Among 12 granulomatous CT lesions 3 cases showed preoperative diagnostic error, which were, confirmed infarction, multiple sclerosis by pathological diagnosis. The pathological findings of 2 vascular lesions that were impressed as infarction and old hematoma were confirmed as granuloma and GBM. The error of preoperative clinical - CT diagnosis was 39% of total 41 patients. The advantage of preoperative stereotactic biopsy is to confirm the correct histological diagnosis, while it can help the patient and surgeon for the planning of further proper therapy.
