68-year-old female was introduced our hospital for productive cough and dyspnea. Chest X ray film showed right upper mediastinal mass and tracheal stenosis. Chest CT showed mediastinal mass with calcifying lesion. ESR at 1 hour was 50 mm and CRP was 1.08 micrograms/ml. Because of progressive dyspnea, the operation was performed without further assessment. We found a mass of adhesive lymph nodes by the side of trachea. We removed it and it turned out to be tuberculous lymphadenitis. Postoperative PPD skin test showed strongly positive reaction. She has taken medication by antituberculous drugs and lives well without complications.
