Cerebral Angiography in “Brain Tumor Suspects”

Abstract

Certain aspects of the technic and value of angiography are discussed. Following a study of angiograms in a group of 42 brain tumors certain characteristics for specific types of tumors emerged, as follows: Arteriovenous angiomas are characterized by a mass of tortuous channels and sinuses fed by large corkscrew arteries and drained by greatly dilated veins. For glioblastomas the most common appearance is increased vacularity at the margin of the tumor with sinuses, irregular dilations and vascular loops within the tumor. In astrocytomas there is a displacement of normal vessels by a relatively avascular area. There is no typical intrinsic angioarchitecture for meningiomas but their circumscribed nature produces specific vascular abnormalities.
