Nasal congestion caused by nasopharyngeal cancer needs to be differentiated from nasal congestion caused by enlarged turbinates to avoid misdiagnosis. It is less likely to be misdiagnosed if it is examined and diagnosed by a specialist in a regular medical institution. Nasopharyngeal cancer is a malignant tumor, and the common clinical symptoms include nasal congestion, blood in the nose, congestion in the ears, hearing loss, double vision and headache. In addition, advanced nasopharyngeal cancer can locally invade important structures and metastasize distantly, and in serious cases, it can lead to life-threatening rupture and bleeding of large blood vessels. Usually, nasopharyngoscopy, CT, MRI and pathological examination can provide necessary diagnostic information, among which pathological examination is the gold standard. Nasal turbinate hypertrophy is mainly an inflammatory lesion caused by long-term inflammatory stimulation of the nasal mucosa, resulting in tissue congestion and edema, hyperplasia and hypertrophy or polypoid changes, which usually results in nasal congestion and runny nose.
