Cerebral cavernous malformation information page.Vascular malformations of the central nervous system. American Association of Neurological Surgeons. They're also more likely to happen again with malformations located in the brainstem. The most concerning complications of CCMs stem from recurrent bleeding, which may cause a hemorrhagic stroke and lead to progressive neurological damage.īleeding is more likely to recur in people with prior diagnosed hemorrhages. These genes are thought to work together to communicate between cells and reduce leaking from blood vessels. It isn't fully understood why these mutations lead to CCM. To date, research has identified three genetic variants responsible for inherited cavernous malformations, to which almost all familial cases of cavernous malformations have been traced.įamilial CCMs are inherited through a mutation in one of these genes: While most CCMs occur with no clear cause, the inherited form of the condition can cause multiple cavernous malformations, both initially and over time. Other rare syndromes may be associated with CCM. Radiation to the brain or spinal cord may also result in CCMs 2 to 20 years afterward. MRI evidence of multiple CCMs without a DVA.Genetic testing is often recommended for people who have: A diagnosis of the inherited form can be confirmed by genetic testing. In many cases, such people can identify similarly affected family members, most often with multiple malformations. However, roughly 20% of affected people have a genetic (inherited) form of the disorder (familial cavernous malformation syndrome). The sporadic form often has an associated developmental venous anomaly (DVA), which is an irregular vein with a witch's broom appearance. Occurrence Handle10.Most CCMs are known as "sporadic form." They occur as a single formation without an apparent cause and without any family history.
