측두골과 후두골에 발생한 거대한 판간내 표피양 낭종 1예

Abstract

Intradiploic epidermoid cyst of the skull is a benign lesion that is derived from the ectodermal cells of the cranium. They are uncommon, benign and slow-growing lesions. They can be located in any part of the skull. The frontal and parietal bones are the most common sites for the cyst; however, the temporal bone, although rarely, is also involved. For good long-term prognosis, correct radiological assessment and complete removal of the tumor with its capsule are essential. We report a patient with an intradiploic epidermoid cyst of the temporal and occipital bone. The tumor was successfully removed via infralabyrinthine approach with surgical microscope and endoscope.
