Intracranial epidermoid mimicking meningioma.
A case of an epidermoid cyst in the frontal base which showed homogeneous high density in noncontrast computed tomography, simulating a meningioma with calcification, is reported. Operative findings and histological examination suggested that this high density was caused by spontaneous hemorrhage into the cyst.
