ABSTRACT
Intradiploic epidermoid cysts are extradural and very uncommon lesions that may occur in all flat bones of the calvarium. The very slow growth rate and the benign histological nature of these tumors explain their long preoperative evolution and the mild neurological signs. We report a giant intradiploic epidermoid cyst of the temporal bone with an intracranial extension into the posterior fossa which was probably responsible for the destruction of the endolymphatic sac and presenting intermittent vertigo and profound hearing loss. It was discovered incidentally during the evaluation of chronic otitis media. Plain film, CT and MRI all demonstrated the characteristic appearances of intradiploic epidermoid cyst. The tumor was totally removed and cranioplasty was performed.
