Toothy craniopharyngioma: a literature review and case report of craniopharyngioma with extensive odontogenic differentiation and tooth formation.

摘要

A young child presenting with a craniopharyngioma (pituitary adamantinoma) demonstrated the rare phenomenon of pronounced odontogenic elements/tooth formation on imaging. The origin of the craniopharyngioma from primitive stomatodeum theoretically facilitates odontogen-esis [1]. Theories of the genesis of this tumour include remnants of the craniopharyngeal duct, squamous metaplasia of anterior pituitary cells and misplaced tissue of the embryonic enamel organ [2]. A literature review documents six cases of craniopharyngioma with tooth formation although none appear to be as extensive as the case presented.
