Intradiploic epidermoid cysts, like epidermoid cysts in other cranial locations, are rare. Approximately 100 intradiploic epidermoids have been reported, involving all of the cranial bones in proportion to their relative sizes. Over half erode through both tables of the cranium, creating variably sized areas of unprotected brain beneath the soft tumor. We report a case of an intradiploic epidermoid cyst of the right parietal bone that was found after minor head trauma.
