====== Venous angioma ======

[[Developmental venous anomaly]] has mostly supplanted the more pedestrian venous [[angioma]]


see [[Developmental venous anomaly]] (DVA).

[[Cavernous malformation]]s (CMs) were difficult to diagnose in the pre-[[MRI]] era. They are invisible on [[angiogram]] and thus the term AOVM ([[angiographically occult arteriovenous malformation]]) was sometimes used. However, the [[venous angioma]] sometimes seen in association with a CM was visible on angiogram, and thus believed to be the source of the hemorrhage seen, even though in reality it was the CM that had hemorrhaged. Thus, venous angiomas were sometimes treated, also with radiosurgery, a management that was soon aborted
