Abstract
Emperic treatment of brainstem lesions without tissue diagnosis based upon the radiological and clinical findings may result in inappropriate therapy. Alternatively, open operative procedures to obtain tissues require a visible surface abnormality to guide biopsy needle and carry the risk of a major surgical procedure in already compromised patients. For these reasons we consider stereotactic biopsy and aspiration for intrinsic brainstem lesion which is safe and reliable method to confirm histological diagnosis and further management strategy.
The study was conducted on 20 patients with brainstem lesions, upon whom 20 stereotactic procedures were performed.
