Sphenoid sinus mucoceles presenting as intracranial masses on computed tomography.
Two cases of mucocele of the sphenoid sinus that presented as sellar and parasellar masses on computed tomography (CT) are presented. One mucocele was isodense while the other was hyperdense (100 Hounsfield units). Neither lesion demonstrated contrast enhancement. By delineating the total extent of the lesions, CT facilitated pre-operative diagnosis and surgical management.
