Magnetic resonance-guided stereotactic biopsy in intracranial lesions.

Background: Findings and statistical data showed that stereotactic biopsy has an effective role in histopathological diagnosis of brain tumors and lesions and accordingly in creating a treatment protocol. Methods: In our clinic, 143 biopsy procedures were performed on 142 patients between 2014 and 2022. Consistency rates were evaluated by comparing preoperative diagnoses with postoperative diagnoses. Results: Postoperative complications occurred in 7 patients. Complications were observed in 2 patients due to surgery. 4 patients died, not related to our surgical procedures. In 8.4% of the patients, a pathological diagnosis was not performed. The correct diagnosis rate is 91.6% in our group. In this study, a magnetic resonance-compatible Leksell frame was used. Conclusion: Because of its high diagnostic value and low morbidity and mortality rates, stereotactic biopsy is a reliable and indisputable neurosurgical technique which is used worldwide.
