Unusual coexistence of an epidermoid cyst with an atypical meningioma: Case report and review of the literature.

Epidermoid cysts are slow growing lesions believed to arise from inclusion of ectodermal elements during neural tube closure, while meningiomas arise from arachnoidal cells; their association has rarely been reported previously.
