Abstract

CLASSIFICATION  IN A MONOGRAPH published in 1936 by Bergstrand, Olivecrona and Tönnis,1 the following classification of the angiomatous malformations and tumors was used by Bergstrand, who wrote the chapter on pathology:

  1. Angioma cavernosum

  2. Angioma racemosum

    • Telangiectasia

    • Sturge-Weber disease

    • Angioma racemosum arteriale

    • Angioma racemosum venosum

    • Aneurysma arteriovenosum

  3. Angioblastoma

  4. Angioglioma

The angiomatous malformations of the brain arc therefore divided into two main groups, the cavernous and the racemose angiomas. The difference between these two groups is that in the racemose angiomas the blood vessels in the malformation are separated by parenchyma and in the cavernous angiomas they are not.Among the racemose angiomas, the telangiectases and Sturge-Weber disease (nevoid amentia) are malformations of capillaries or precapillary blood vessels and are well defined anatomic and clinical entities. This cannot be said of the last three types of the racemose angiomas. In the arterial racemose angiomas, both feeding and draining vessels should theoretically
