Abstract
Six [human] cases of cerebral venous angioma are reported, and the angiographic findings, clinical symptoms, EEG foci and histological features are compared to those in 26 previously reported cases. The so-called venous angioma has little clinical significance; neither arteries nor capillaries are involved in this type of vascular malformation. The small, dilated veins which develop secondarily are due to an abnormality in venous development during embryogenesis.
