Preoperative computed tomography (CT) images of the orbit. Axial (A, B) and coronal (C, D) CT images show a well demarcated mass surrounded by a bony perimeter of the middle turbinate (arrow) at right nasal cavity. Medial orbital wall is destructed and nasal septum is deviated to the left side. The medial rectus muscle and orbit is displaced laterally. Total opacification is noted in right ethmoid sinus (asterisk) and frontal sinus.
