A 56-year-old woman presented with a several-year history of nasal obstructive symptoms and anosmia. Despite previous courses of fluticasone propionate, she experienced no improvement. She had no associated pain, rhinorrhea, headaches, changes in vision, or epistaxis, and her medical history was negative for either allergic rhinitis or chronic rhinosinusitis. Findings from the physical examination were notable for bilateral, obstructing nasal masses arising from the superior nasal cavity (Figure, A).
