Suprasellar epidermoid.

Clinical analyses of six cases of suprasellar epidermoid were made in order to define specific clinical and radiological manifestations and thus improve the preoperative diagnosis. The tumours are seen as avascular suprasellar masses. Pre-operative diagnosis of suprasellar epidermoid is not easy and it may be misdiagnosed as a craniopharyngioma. They tend to be much more extensive than craniopharyngiomas. It is necessary to keep in mind the possibility of suprasellar epidermoid in the differential diagnosis of a suprasellar mass.
