The angioarchitecture of the astroblastoma

The angioarchitecture of an astroblastoma of the corpus collosum is studied on serial carotid angiograms, made during life, and on post mortem angiograms, performed by filling of the cerebral arterial system with a colloidal bariumsulphate solution and by using the translucidation technique. The results of these investigations are compared to the histological aspect of the tumour. This study reveals the close relationship between the astroblasts and the bloodvessels. The angioarchitectural pattern of this tumour is characterized by new formation of capillaries. It is considered as an additional support to classify the astroblastoma as a separate type of glioma.
