Cavernous malformation (CM), also known as cavernous angioma, cavernous hemangioma and cavernous vascular malformation, is a type of vascular malformation that occurs in the brain and/or spine. These malformations are made up of fragile arteries and veins that tend to leak small amounts of blood and can cause large brain hemorrhages resulting in permanent neurological deficits, if not treated.
Most people who have CM are born with them. However, the malformation can change over time, causing onset of symptoms later in life. CM can also run in families. Our team at Stanford Hospital & Clinics is experienced in screening and treating multiple generations of a family.
