An expansile osseous lesion is noted filling the right nasal cavity with some cystic changes. It is mainly epicentered upon the right ethmoid air cells. It exerts mass effect with bowing of the nasal septum and the medial wall of the right orbit narrowing the orbital apex.
The right maxillary sinus is opacified with retained secretions, mostly due to obstruction of the ostiomeatal complex by the right sinonasal mass.
