[Comprehensive investigation on fifty meningiomas (author's transl)].
In order to increase the accuracy of preoperative "type-diagnosis" fifty meningiomas in various sites were investigated by brain-scan, and routine angiography. Some cases in addition had external carotid angiography and angioscintigraphy of the external and internal carotid. By tabulating the findings, it is possible in 90% of cases to provide a pre-operative "type-diagnosis" of meningioma. Details are given regarding the influence of the tumour site on the ability to demonstrate the tumour through branches of the external or internal carotid, as well as "filling defects" or isotope uptake in angioscintigraphy. The reasons are discussed for the lack of agreement about the size of the tumour, in angiogram and angioscintigram, as well as in the brain-scan, in 15 out of 34 meningiomas.
