简要总结
This is an observational prospective study. Role of EBUS-TBNA (endobronchial ultrasound transbronchial needle aspiration) is evaluated to diagnose tuberculosis in mediastinal and/or hilar lymph nodes.
The investigators analyse the specificity and sensibility of this technique to diagnose tuberculosis in mediastinal and/or hilar lymph nodes.
Patients with mediastinal and/or hilar lymph nodes on X-ray or CT thorax where a tuberculosis is the most probable cause and who have no parenchymal lesions suspected for tuberculosis and without other lymph nodes that are more easily accessible or palpable will be included in this study.
