Mediastinal lymphadenopathies may occur due to benign or malignant diseases. While most of the benign causes are granulomatous diseases (mostly tuberculosis, sarcoidosis and reactive hyperplasia) the leading malignant cause is metastatic lung cancer. Mediastinal lymph nodes can be evaluated by imaging methods, minimally invasive procedures (EBUS, EUS, EUS-B) and invasive (mediastinoscopy) procedures. Nowadays mediastinoscopy is usually used to exclude false-negative results before curative surgery in EBUS/EUS negative NSCLC patients. Minimally invasive endosonographic methods are used in increasing numbers as they have high sensitivity and spesificity in both diagnosis and staging; and also they are safe and reproducible.
