Midline dermoid cysts are uncommon lesions that can lead to severe complications when an intracranial extension exists. We report the cases of two twin sisters referred to surgery for removal of the masses and the intracranial extension. They represent an additional example of familial nasal dermoid cysts, providing further support for a genetic basis for the disorder.
Keywords: intracranial extension; midline dermoid; nasal masses; twins.
