Cavernous malformations hemorrhage

Vascular malformations of the brain are usually divided into arteriovenous malformations, capillary telangiectasias, venous malformations, and cavernous malformations. However, for a long time, the term angiographically occult vascular malformation or cryptic (Cohen et al. 1982 Dillon 1997 Wilson 1992) has been used to describe those vascular malformations that could not be visualized angiographically, but obviously were able to cause intracerebral hemorrhage.
