Are cysts on the brain hereditary?

Most diagnosed cases of arachnoid cysts are sporadic - occurring in people without a family history of arachnoid cysts. However, familial cases of arachnoid cysts have been reported in the medical literature, suggesting that a genetic predisposition may play a role in some people.
