case_images: CT findings of the patient. (A) Coronal CT scan at presentation showed severe maxillary and ethmoidal sinusitis as well as marked inflammatory swelling of soft tissue in the right cheek and temporal region. Intraorbital soft tissue inflammation and thickening of the lateral rectus muscle of right eye were also observed. (B) Axial CT scan taken 1 day after sinus surgery showed severe tenting of the posterior part of globe (arrow) and stretching of the optic nerve due to severe proptosis.
