Cavernous malformations, also known as cavernous angiomas or cavernomas, are abnormal clusters of dilated blood vessels ranging in size from microscopic to inches in diameter. Made up of little pockets, or “caverns,” they’re filled with blood and lined with a thin layer of cells called the endothelium. These malformations can cause seizures, stroke symptoms, hemorrhages and headaches.
They can be found anywhere in the body, including the liver, rectum, kidney, eyes, nerves, spinal cord and brain. Those that develop in the brain or spinal cord – called cerebral cavernous malformations – are the most serious.
Cavernous malformations occur in about 1 in 200 people, affecting men and women almost equally and people of all races, and ages. In some cases, they run in families and are inherited.
