Cavernous malformations are also known as cavernous angiomas, cavernous hemangiomas, cerebral cavernous malformations or cavernomas.

It is a condition in which clusters of blood vessels in your child’s brain or spinal cord form abnormally, creating ‘caverns’ filled with slow-moving blood.

Some cavernous malformations cause no symptoms, but larger cavernomas may cause headaches, seizures, and impaired speech or vision.
