Computed tomography of the sinuses showed (1) an abnormal soft-tissue process causing expansion of the right maxillary sinus with complete opacification of the right maxillary antrum, (2) widening of the right ostiomeatal complex with mucosal thickening in the right-sided ethmoidal sinus cells, and (3) no violation of the bony wails separating the sinuses from the orbit or intracranial cavity (figure 1, A and B).
