Stereotactic biopsy of intracranial space occupying lesions.

摘要: The results of stereotactic biopsies intracranial expanding lesions with narrow instruments both prior to and during the CT era are evaluated in 345 patients. Eighty-four cystic were needled roughly classified. Small, cystic, or solid tumours anatomically well-defined areas such as sellar, third ventricle, pineal regions easily punctured classified without scanning. When larger different compartments biopsy verification rate increased from 55% towards 91% if an enhanced investigation was included. A is a fairly safe procedure, yielding this series mortality less than 1% morbidity 2.3%.
