Recurrent epistaxis, etiology presumed to be from right polypoid nasal mass. There is packing material in the right nasal cavity with low T2 and intermediate T1 signal suggestive of imbibed blood products from epistaxis. There is markedly swollen mucosa within the right maxillary sinus that communicates with a polypoid lesion within the posterior right nasal cavity and nasopharynx via an accessory ostium. The airway is otherwise intubated. There is diffuse mucosal thickening within the bilateral and sphenoid sinuses, right more than left. The orbits and imaged intracranial structures are unremarkable.
