Unlike the majority of sinonasal carcinomas, SNUC possess an uncertain histological origin and pleomorphic composition. Their heterogeneous composition prohibits their distinction from other more commonly encountered nasal tumors on the basis of imaging alone. Patients afflicted with SNUC often complain of symptoms of chronic, progressive sinus congestion, and epistaxis. Imaging studies of SNUC often illustrate rapidly enlarging masses involving multiple sinonasal sites with frequent evidence of extension beyond the sinonasal tract. Orbital extension is a frequent finding encountered during radiographic investigations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Report.<\/jats:title>\n                    <jats:p>A 28\u2010year\u2010old white man presented complaining of diplopia in superior gaze, pain on eye movement, and gaze\u2010evoked amaurosis which progressed during a 2\u2010day period. Funduscopic examination revealed choroidal folds in the papillomacular region OS. Magnetic resonance imaging (MRI) revealed a 3 cm \u00d7 3.5 cm \u00d7 4 cm mass emanating from the left ethmoid sinus with bony destruction of the left orbital floor, nasal wall of the left and right orbits, and the cribriform plate. A transcutaneous aspiration fine\u2010needle biopsy confirmed the presence of a SNUC. After a 7\u2010wk course of combined chemoradiotherapy marked regression in the mass was attained with resolution of the ophthalmic symptoms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion.<\/jats:title>\n                    <jats:p>SNUC is an aggressive malignancy that is often discovered in its advanced stages after having afflicted serious insult on the nasal and sinus cavities.
