Cavernous Malformation: Questions & Answers

A doctor has just told you that you or a loved one has a cavernous malformation. It’s normal to have a lot of questions.

This page is for you if your doctor diagnosed you or a loved one with one or more cavernous malformations in your brain or spinal cord. Your doctor may have used the terms cerebral cavernous malformation (CCM), cavernoma, cavernous malformation, or cavernous angioma. These are all names for the same thing. On this page, we use the term cavernous malformation.

This page will help you understand the condition and make informed choices about your care. You may want to share this page with family members or others who care about you so they can better understand the condition.

Understanding CCM





Ross

Patient Story: Ross

Epilepsy and CCM3

When Ross was ten years old, he had his first seizure in the school yard and was rushed to the hospital, where he had two more seizures in the emergency department. Ross was diagnosed with epilepsy that day. Seizures reshaped Ross’s life in several ways, both big and small. He had to give up playing rugby due to the risk of head injury, and frequent seizures made it difficult to continue playing the other sports he loved. The side effects of his medications also impacted Ross’s academic performance in school. Doctors worked to identify a single lesion causing his seizures — but with multiple lesions and a rare CCM3 mutation, surgery has not been an option. Through it all, Ross found music. He picked up a guitar shortly after his diagnosis and earned a university degree in music and songwriting. Today, he is pursuing further education in Composing Music for Film, and he teaches guitar to young students in Dublin. Ross holds onto the hope that researchers will find a treatment for others living with active epilepsy.





Vanessa

Patient Story: Vanessa

When Cavernous Malformations Cluster Around a DVA

Vanessa was two weeks into her second semester at fashion school in New York City when a brain bleed changed her life. An MRI traced the bleed to a cerebral cavernous malformation in her thalamus (a part of the brain that helps control movement and sensation), with two more nearby. All three lesions were clustered together around a developmental venous anomaly (DVA), which is not uncommon with cavernous malformations. The bleed caused hydrocephalus, a dangerous buildup of fluid in her brain, and within days Vanessa had emergency VP shunt surgery. It was the beginning of years of repeated bleeds, ER visits, and uncertainty.

Adapting to lasting changes

That first bleed left Vanessa with lasting disabilities, including dystonia (involuntary, painful muscle contractions) on one side of her body and severe ataxia, which causes shaking and coordination challenges. Together, these make walking and everyday tasks hard. Even so, Vanessa stayed committed to her goals. She continued her studies at a slower pace and graduated, walking at commencement with her cane.

A year later, another bleed made her symptoms worse, and she was no longer able to work. A few years after that, a new bleed caused facial paralysis that lasted two months, and her care team revisited the idea of surgery. Because Vanessa’s lesions are deep in the brain and the nearby DVA requires extra consideration during surgery, her options were limited. She chose laser interstitial thermal therapy (LITT), a less invasive laser procedure.

Vanessa today

Today, Vanessa lives with the daily challenges caused by her CCM. It has changed the course of her life, and the hard days are very real. Still, she keeps working toward her goals, including getting stronger through therapy and returning to work someday. She holds on to what she loves, from makeup artistry to travel and concerts, and has found steady support in the Alliance community. Giving up isn’t in her nature, so she keeps showing up for her life.

Bleeding (hemorrhage)




John

Patient Story: John

Living with a Spinal Cavernous Malformation

John had already lived with a cavernous malformation diagnosis for four years when he boarded a flight home from a family trip. His brainstem CCM had bled once, leaving him with symptoms that improved over months but never fully resolved. He had learned to live with them.

On the way home, he started to feel like something was wrong with his legs. By the time the plane landed, he couldn’t walk without using his suitcase as a crutch. “We went straight to Massachusetts General Hospital, where I was helped into a wheelchair. That is the last time I stood up.”

A second bleed

Doctors confirmed a second bleed, this time in his spinal cord. As a familial CCM patient, John knew multiple lesions came with the territory. He just didn’t know one of them was in his spine. Two days after that flight, he was completely paralyzed from the waist down. He spent two months between the hospital and a rehabilitation center before returning home.

John today

Life looks different now, but it is still full. John has found a love for adaptive sailing. He spends time with his family, and his grandkids bring him particular joy. And he joined the Board of the Alliance to Cure Cavernous Malformation, channeling his experience into raising awareness and pushing toward a cure. Other lesions remain, and the possibility of another bleed is always present. But John has chosen to meet that uncertainty with action.

Your care and treatment







Joyce

Patient Story: Joyce

A CCM1 Journey

In 2004, Joyce learned that she had multiple cavernous malformations in her brain and spine. After genetic testing, her doctors told her that a mutation in the CCM1 gene is the cause. This specific change is known as the Common Hispanic Mutation (scientific name: CCM1 c.1363C>T, p.Q455*).

People of any background can have familial cavernous malformations. Sometimes, families who are connected through a distant ancestor share a mutation. This is called a founder mutation. The families with the CCM1 Common Hispanic Mutation can trace their roots to early Spanish settlers in New Mexico. Many of these families still live in New Mexico today. In fact, more people with cavernous malformation live in New Mexico than anywhere else in the world.

Raising awareness in New Mexico

Joyce spent 15 years identifying the founding families of the mutation in New Mexico. Joyce works to raise awareness across New Mexico by speaking at patient conferences and public workshops. She shares her story with local and national media. She also supported legislation to educate more doctors about cavernous malformations in the state of New Mexico, leading to dedicated funds for research and care at the University of New Mexico.

Joyce today

Joyce has not been symptom-free. She had spinal surgery shortly after her diagnosis. Other cavernous malformations have had new and worrisome effects. She has been hospitalized from time to time. So far, she has not had another surgery. Joyce does not let the disease slow her down.

One of Joyce’s biggest reliefs is that her children did not inherit the condition. Still, Joyce continues her advocacy to support the many New Mexicans who continue to face challenges. “It helps a patient to become their own advocate,” Joyce said. “Once people start talking to each other, it doesn’t seem so scary.”

Pregnancy & Children




Kathryn

Patient Story: Kathryn

Brainstem CCM in Childhood

At seven years old, Kathryn was helping her family sell Girl Scout cookies when her mom, Amber, noticed something was wrong. Kathryn’s smile had gone lopsided, she was stumbling over simple math, and when Amber asked her to close her eyes and hold her arms out, her right arm dropped. Amber recognized the signs of a stroke immediately and got her to the emergency room. Scans found the cause: a cavernous malformation in her brainstem that had bled, and Kathryn needed surgery.

Getting expert opinions

Because of where the lesion was, it was a tricky case, and the family got opinions at two of the Alliance’s CCM Centers: Lurie Children’s Hospital in Chicago and Barrow Neurological Institute. They had a great experience at both, with each team offering honest, genuinely helpful advice as the family worked through the best path forward for Kathryn. They ultimately decided to move forward with surgery at Barrow, where the surgical care was excellent. Dr. Michael Lawton removed the lesion, and Kathryn came through brainstem surgery without any new neurological deficits.

Kathryn

Kathryn today

Recovery has not been easy, and Kathryn continues to face some ongoing challenges, including weakness on her right side. But she’s back to being a kid: dancing, playing violin, doing Girl Scouts, and playing volleyball and softball, pushing through frustration on the days she can’t quite keep up with her teammates. “We can do hard things” has become something of a family motto. Her family is grateful for the guidance and the surgical skill that CCM Centers brought to Kathryn’s care.
