Cavernoma

Make an Appointment

Cavernomas, also called cerebral cavernous malformations (CCMs), cavernous angiomas or cavernous hemangiomas, are enlarged and deformed blood vessels gathered into clusters. These clusters (angiomas) may look bubbly, like raspberries. They appear in the brain, spinal cord or other parts of the nervous system and body, including on the skin and eye. There are two forms:

  • Sporadic — most common. Usually, only one cavernoma develops and the condition doesn’t run in your family.
  • Familial — less common. Usually, multiple cavernomas occur and the condition runs in your family (Hispanic-American families from the Southwest are most often affected). 

Cavernomas sometimes leak blood and cause neurological issues, such as arm or leg weakness or problems with your vision, balance, memory or attention. They are a cause of stroke in young patients.

Cavernoma Excellence at UVA

Designated as a Clinical Center by the Angioma Alliance, we provide high-quality care with a team that includes neurologists, neurosurgeons, skin specialists, imaging specialists and genetic counselors. We’re the only recognized Clinical Center for cavernoma care in the mid-Atlantic and Southeast regions.

Treating Cavernomas

Cavernomas are diagnosed using magnetic resonance imaging (MRI). Treatment for cavernomas includes:

  • Medication — If you are having seizures, you may be given medications to stop them.
  • Surgery — You may need surgery to remove your cavernoma if you're experiencing symptoms.
  • Genetic testing and counseling — If cavernomas run in your family, we may be able to identify the affected genes. We may also be able to determine if you have family members with the affected gene.

Most cavernomas do not need surgery. If you aren’t having symptoms, your healthcare provider will use MRI to monitor for any changes in your cavernoma.

How Do I Know if I Have a Cavernoma?

Usually, you won’t know until the cavernoma causes a seizure. Sometimes they are found when you get brain imaging for other reasons. Symptoms generally appear when cavernomas bleed, and they may include:

  • Seizure
  • Sudden headache
  • Nausea and/or vomiting
  • Weakness or numbness on one side of the body
  • Difficulty speaking or understanding speech
  • Double vision or loss of vision
  • Balance problems

Cavernomas on the skin are often seen in cases of familial cavernoma. They usually appear on your arms or legs, and have the same bubbly, berry-like appearance.

What Should I Bring to My Appointment?

For your first appointment, you should bring any previous brain imaging, like MRIs or CT scans, with you.

If you can, you should also ask your biological parent(s) the following questions, and bring the answers with you:

  • Have you been diagnosed with a cavernoma?
  • Have you ever had seizures?
  • Have you ever had a stroke?

  • Do you have a history of headaches?
  • Do you have siblings (brothers and sisters)? If so, do they have a history of seizures, headaches or strokes?
  • Do you know where your ancestors came from?
