5. Cerebral cavernous malformation
Frequently asked questions
No. It is a vascular malformation made up of abnormal blood vessels.
No. Monitoring or treatment depends on symptoms, bleeding history and location.
Yes, some cavernomas are associated with seizures; assessment is individual.
Multiple lesions or a family history may warrant discussion of a hereditary form with your clinician.
A cavernoma, or cerebral cavernous malformation, is a cluster of abnormal small blood vessels in the brain or spinal cord. Some are found incidentally. Others may be associated with seizures, headache, bleeding or symptoms related to their location.
MRI is central to diagnosis. Symptoms, location, previous bleeding and family history inform assessment. Multiple lesions or affected relatives may prompt consideration of a hereditary form.
Some asymptomatic cavernomas can be monitored. Medication may be used for seizures. Surgery may be considered for a symptomatic or bleeding lesion when the expected benefit outweighs the neurological risks of its location. Risk is not the same for every lesion.
