A 75-year-old man presented with a 2-month history of progressive right-sided nasal obstruction and bleeding. He had received antibiotic treatments, without significant improvement. His nose bleeds had continued even though he had stopped taking antiplatelet medications. He had no known history of paranasal sinus disease. His medical history was remarkable for arterial hypertension and coronary artery disease. He had undergone a coronary artery bypass grafting procedure 1 year before presentation.
