title: Experiences with CT-guided stereotaxic biopsies in 121 cases.
abstract: Needle biopsy using a CT-guided stereotaxic technique was performed in 121 cases of suspected brain tumour. Using this technique, it is possible to perform biopsies safely and accurately on even small and deep-seated lesions with a minimum of surgical intervention. However, accurate diagnoses are sometimes not possible when only a small number of viable cells are obtained, such as in lesions containing old haematoma, cystic tumours, previously treated tumours or tumours which are either too hard or too soft. We were able to make accurate diagnoses in 98 of our 121 cases (81%). The accuracy of diagnosis is somewhat hampered by the small volume of sample material obtained using this biopsy technique, and this fact should be kept in mind when evaluating the histological material.
