It is clinically possible to detect tuberculosis by bronchoscopy. Especially for very atypical radiographs of the lungs, or CT or MRI, many times it is not possible to see that there is a tuberculous lesion in the lungs. One needs to consider other sites with TB lesions, such as the bronchial mucosa. Tracheoscopy can be done to be able to detect tuberculous lesions in the tracheobronchial mucosa and can be used to diagnose endobronchial tuberculosis. Biopsies can be taken, pathology can be done, and cultures of Mycobacterium tuberculosis and even drug sensitivity tests can be done. It is possible to confirm the diagnosis and also to select relatively sensitive anti-tuberculosis drugs to adjust the treatment plan.
