What causes a cavernoma?

In most cases, there's no clear reason why a person develops a cavernoma. The condition can sometimes run in families less than 50% of cases are thought to be genetic.

However, in most cases cavernomas occur randomly. Genetic testing can be carried out to determine whether a cavernoma is genetic or whether it's occurred randomly.

Some cavernoma cases have also been linked to radiation exposure, such as previously having radiotherapy to the brain, usually as a child.
