Tuberculosis of the nasal cavity and nasopharynx is extremely rare. The diagnosis is frequently delayed because of unfamiliarity with the disease. It is difficult to make an accurate diagnosis of tuberculosis of the nasal cavity and nasopharynx on imaging findings alone; a biopsy is required to confirm the diagnosis and to differentiate it from malignancy and the other conditions. The authors have experienced 6 cases of tuberculosis of the nasal cavity and nasopharyx. We report them with review of literatures.
