Stereotactic biopsy in brain lesions not amenable to microsurgery

Abstract

Introduction Brain tumors represent an important cause of morbidity and mortality, and some cases are frequently difficult to treat. However, development of noninvasive imaging techniques like MRI/magnetic resonance spectroscopy has improved the diagnostic accuracy. Aim Stereotactic biopsy was performed for tissue diagnosis. Patients and methods A total of 50 patients with deep-seated brain lesions, at eloquent area or multiple brain lesions, by MRI study, were biopsied using frame and frameless stereotactic procedures between the periods of September 2016 and October 2019. Results During the study period, our diagnostic yield was 94.0%. Conclusion Either frame or frameless stereotactic biopsy is a minimal invasive method for accurate diagnosis in deep-seated brain lesions.
