A 51-year-old man presented with a 1-month history of nasal obstruction, green malodorous nasal discharge, facial pain, and facial fullness. He underwent an unenhanced computed tomographic scan of his sinuses, including a scout image (Figure 1) and a coronal reformatted image (Figure 2). After a 2-week course of amoxicillin and clavulanic acid, his symptoms improved. Video nasal endoscopy showed moist nasal mucosa with no purulent discharge and no nasal polyps. The patient's medical history was remarkable for obstructive sleep apnea controlled with continuous positive airway pressure and the placement of 3 dental implants 5 months before presentation.
