BackgroundFrame-based stereotactic biopsy has proven to be a safe procedure with a high diagnostic yield for patients. Different supratentorial localizations can easily be accessed by standardized stereotactic approaches. Cerebellar and brainstem lesions, however, are not easy to reach because the positioning of the frame pins often makes it impossible to address the entry point properly.MethodsBy oblique positioning of the frame, cerebellar and brainstem lesions also can easily be accessed to take tissue samples.ConclusionModification of the standardized positioning of the frame allows for safe and straightforward stereotactic access even to cerebellar and brainstem lesions.Copyright © 2016 Elsevier Inc.
