- Cerebral cavernous malformations (CCMs) are irregular bundles of tiny blood vessels in the brain.
- Although this condition is rare, it can be life-threatening and may lead to long-lasting health problems.
- It’s primarily a genetic condition and may be treated with medication. In serious cases, surgery may be necessary.
Cerebral cavernous malformations, also known as CCMs, are abnormally formed blood vessels. While this might give you pause for concern, it is rare, occurring in 0.2-percent of the general population. However, in severe cases, this condition can be life-threatening and may lead to long-lasting health problems, which is why it’s important to get informed.
But first, we should explain what this condition means, and who it affects. That way, you will have a better understanding of the condition and visit a doctor if you have concerns (or call 911 for serious complications). Here’s everything you need to know about cerebral cavernous malformations…
What Are Cerebral Cavernous Malformations?
As WebMD puts it, CCMs are “irregular bundles of tiny blood vessels (capillaries) in the brain.” More specifically, it notes that the vessels are stretched out more than the norm, which leads to their walls being prone to leaking.
The CCMs can range in size from about a 1/4-inch to 4-inches, says the source. It also explains that the vessel walls “also lack certain fibers that normally make blood vessels able to stretch out and then stretch back,” causing their shape to change with high blood flow. The vessels then end up in “odd open spaces” referred to as caverns.
