OPTIC ATROPHY CAUSED BY AN ARTERIOVENOUS ANGIOMA

Abstract

CUSHING and Bailey,¹ in a monograph published in 1928, completely reviewed the literature and contributed their own experiences with tumors arising from blood vessels of the brain. Dandy² in the same year contributed two papers on the same subject. Thus, this subject was clarified and a solid base was formed for further work. Cushing and Bailey¹ divided the tumors of cerebral blood vessels into two groups: (1) the angiomatous malformations and (2) the hemangioblastomas, or true neoplasms of blood-vessel elements. The malformations were further subdivided into (1) telangiectases, chiefly capillary; (2) angioma venosum, chiefly venous, and (3) angioma arteriale, arteriovenous. The angioma venosum group was further subdivided into (a) the simple varix; (b) the serpentine varix, superficial, and (c) the racemose, or cirsoid varix—a congeries of deep-seated vessels. The angioma arteriale was subdivided into the serpentine and the racemose, or cirsoid, type. Dandy^2a suggested that the
