Figure 2

Sagittal views: postcontrast images of (a) CT facial bones and (b) MRI facial bone T1-weighted sequence which reveal the craniocaudal extent of a left nasal cavity heterogeneously enhancing mass with mild protrusion of the posterior border into the sphenoid sinus and superior nasopharynx (solid arrows). The pituitary gland (curved arrows) can also be seen with a similar enhancement pattern to that of the left nasal cavity mass.
