Diagnostic yield of stereotactic needle-biopsies of sub-cubic centimeter intracranial lesions

摘要

Background:Stereotactic brain biopsies are widely used for establishing the diagnosis of intracranial lesions. Here we examine whether stereotactic biopsy of smaller brain lesions, defined for this study as being less than 1 cubic centimeter (1 cc) in volume, are associated with lowered diagnostic yield.
