[Diagnostic classification of intracranial meningiomas in the serial angiogram].
On the basis of 70 serial angiograms of surgically and histologically reliably diagnosed intracranial meningiomas and the appertaining general radiographs of the skull the following was found: 48.5 per cent of the general radiographs showed reactions, 7.1 per cent showed tumour calcifications. Basal meningiomas of the anterior and medium cranial fossae and meniogiomas of the wings of the sphenoid bone are supplied by the a. carotis interna, that is to say, they are also diagnosed by the internal carotid angiography. In serial angiograms, classification was possible in 74 per cent. The other supratentorial meningiomas require angiographies of the external or the common carotid. Infratentorial menigiomas were diagnosed in 50 per cent of the angiograms. The "early vein" is no reliable sign of malignity of the menigiomas. The same applies to "apthologic vessels", "shunts", etc. Staining does not give any secure indications of histological structures.
