Dense Intracranial Epidermoid Tumors

Abstract
Epidermoid [human] tumors may appear as sharply marginated, dense lesions measuring 80-120 Hounsfield units on noncontrast CT [computed tomography] scans rather than as the homogeneously lucent lesions measuring -8 to +32 Hounsfield units previously described. The characteristic density range and the lack of contrast enhancement distinguish dense epidermoid tumors from other lesions.
