title: [Preoperative approach to the histologic diagnosis of cerebral tumors by combination of clinical and paraclinical examinations (EEG, computerized cerebral tomography, scintigraphy, and angiography)].
abstract: The authors present their last series of one hundred operated cerebral tumors (19 meningiomas, 16 benign gliomas, 38 malignant gliomas, 20 isolated metastasis, 8 diversified tumors) studied on the clinical, E.E.G., isotopic scanner, computorized tomographies and angiographic point of view. The comparison of these multiple exams, permits one to determinate the malignant of benign nature of a tumor in 86 p. 100 of the cases and the precise histological nature in 56 p. 100 of the cases. The biopsy effectuated in stereotaxic conditions permits to solve the problem in uncertain cases. The interest of computorized tomography is emphasized (discovery or confirmation of a suspected tumor, definition of its extension in depth), but this recent technic is incapable of constant confirmation of the histological diagnosis; it cannot replace other confirmed methods of diagnosis. The angiography remains necessary to guide the surgical gesture.
