title: Infrasellar craniopharyngioma originating from the pterygopalatine fossa with invasion to the maxillary sinus.
abstract: Craniopharyngiomas that originate in the nasopharynx and sphenoid bone (known as infrasellar craniopharyngiomas) are rare and comprise only 5% of all craniopharyngiomas. The involvement of the maxillary sinus has been reported only twice. We present a very rare case that involved the maxillary sinus.
