Epidermoid tumor of unusual expansion at the skull base

Abstract

The case of an epidermoid tumor of unusual extension at the skull base is reported. Various and comprehensive radiologic examinations are described and the difficulty of diagnosis of rare brain-base prosesses is shown.

Although neuroimaging with CT scan, CT cisternography, angiography and MRI was carried out on adequate diagnosis could not be made so that the question of operability could not be answered. In this case MRI did not prove to be more sensitive than other traditional radiologic examinations for the primary diagnosis, postoperative control, or clarification of suspected recurrence.
