Abstract:
Epidermoid cysts are rare congenital tumours representing less than 1% of all intracranial tumours. They are derived from the development of abnormally situated ectodermal tissue and are often an incidental finding. We report a case confined to the base of the skull, responsible for an extradural mass.
