[The angiographic demonstration of the arterial component of large meningiomas in the cerebral cortex and medulla (author's transl)].

The arterial architecture of large meningiomas were studied in the cerebral cortex of medulla by selective arteriography of internal and external carotid arteries, or the common care in 12 patients. The findings were compared with operative observations (or in one case with the autopsy result), and were related to the histological and pathological findings. The origin of the supplying vessel was found to be significant in the differential diagnosis.
