Abstract
Carniopharyngiomas are usually located in the intracranial cavity, predominantly at the suprasellar region although they may be found at times within the sella. However, craniopharyngiomas developing in the nasopharynx and the sphenoid sinus, have been very exceptionally reported.
Recently the authors have experienced two cases of such a rare localization. The first one is the case that invaded and destructed the floor of the middle fossa and nasopharynx, originating in the sphenoid bone. The second one is the case that formed a large cyst in the sphenoid sinus.
This report includes the demonstration of clinical menifestations, clinico-pathological differentiation as well as bibliographical discussions of these two rare cases.
