Intracranial epidermoid tumor: discussion of four cases

Four cases of intracranial epidermoid tumor are presented. These are uncommon tumors with no specific signs or symptoms, and their diagnosis depends upon a high index of suspicion. Computerized axial tomography (CAT scan) was helpful in diagnosing one of the cases described and undoubtedly will be instrumental in identifying future cases. Epidermoid tumors are biologically benign. They are often amenable to resection, and therefore tissue diagnosis before starting any therapy is important.
