Tuberculosis Antibody and Tuberculin Positive Tests Initially Misdiagnosed as Active Tuberculosis in a Broncholithiasis Patient with Recurrent Hemoptysis and Fever Proven by Lung Lobectomy.

Background: To report a case of broncholithiasis with recurrent hemoptysis and fever initially misdiagnosed as active tuberculosis. Methods: The chest contrast-enhanced CT scan, electronic bronchoscope, and ultrathin bronchoscope were performed leading to the diagnosis of broncholithiasis, open lung lobectomy was done after thoracic surgery consultation. Results: The chest contrast-enhanced CT scan showed a high-density intratracheal shadow and calcified lymph nodes. Ultrathin bronchoscopy manifested calcified lesions located at the distal portion of the right lower lobe bronchus. Histopathology of lobectomy showed lithiasis in the right lower lobe tracheobronchial tree. Conclusions: We should pay attention to calcified intratracheal lesions and make differential diagnosis with tuberculosis, especially when accompanied with calcified lymph nodes and fever.
