Quiste epidermoide intradiploico parietal izquierdo. A propósito de un caso y revisión de la literatura

Abstract

Epidermoid cysts are congenital benign, slow growing tumors, that account for 1% of all intracraneal tumors. In 25% of the cases they have an intradiploic localization an are exceptionally infratentorial. We present a 7-year-old escolar patient who presented a growing bulging of the scalp, associated with insidious, holocraneal, low intensity headache. The patient had personal history of migraine and epilepsy with complex partial seizures. Imaging studies reported a well-defined ovoid mass in the left parietal bone with lytic characteristics and 8,8x17mm of diameter. The surgical procedure was successful and the removal of the whole tumor was accomplished. Histopathological studies reported an epidermoid cyst.
