  • Abstract
  • Look Inside

 Computed tomography (CT) was used for the diagnosis of an ethmoidal and a sphenoidal cyst in two cases. These cysts presented slightly high density or isodensity in the preoperative CT scanning, and they protruded into the orbital cavity. In the postoperative CT scanning, the ethmoidal and sphenoidal area in these cases showed low density and the protrusion into the orbital cavity disappeared. CT showed the outline and the content of the cysts clearer than the conventional x-ray examinations.

 CT is an useful examination for the diagnosis of the cysts in the ethmoidal and sphenoidal regions.
