Cavernous Malformation

Why Choose Florida Hospital?

Many people who have a cavernous malformation—or abnormally formed blood vessels that have thin walls and lead easily—will never have any symptoms, and may not even know they have this conditions. For others, however, a cavernous malformation can be much more serious, and in a few cases can rupture, leading to stroke and even death. The doctors at Florida Hospital are experts in assessing and diagnosing neurological conditions such as cavernous malformation, and can help figure out if your headaches and seizures are caused by this condition or something else, and figure out the best treatment regimen for you.

A cavernous malformation, sometimes called a cavernoma, cavernous angioma or cavernous hemangioma, occurs when there are abnormally formed blood vessels; specifically, tiny blood vessels called capillaries group together, growing extremely thin walls that leak easily. These lesions, as they’re called, can form anywhere in the body, but are most likely to cause symptoms, such as headaches or seizures, when they occur in the spinal cord or brain. In a few cases, lesions can rupture and bleed into the brain, causing stroke or death.

About 1 percent of people have a cavernous malformation, which forms before or soon after birth, and may come and go. About half of them have a cerebral cavernous malformation (CCM), meaning a malformation in the brain, though one quarter of these individuals will never have symptoms. Many—though not all—cases of cavernous malformation appear to be inherited.
