Definition of abbreviations: Ca = cancer; ENB = electromagnetic navigation bronchoscopy; NSCLC = non–small cell lung carcinoma.

^*Regression or not changing of the lesion by CT follow-up (n = 2) in 5 and 3 mo of follow-up, respectively; stable lesion (n = 1) in 2-mo period confirmed as hamartoma based on CT and nonspecific pathology; stable lesion (n = 1) in 4-mo period looked like granulomatous disease, surveillance CTs were planned by 6 mo; stable lesion (n = 1) in 3-mo period in a patient with HIV/AIDS, Mycobacterium avium intracellulare grew in his sputum culture.

^†Hepatocellular Ca (n = 1), metastatic adenocarcinoma (n = 1).

^‡ENB reached the target lymph nodes, diagnosis was also supported by bronchoalveolar lavage in two cases, granulomatous tissue from lymph node compatible with sarcoidosis obtained in one case.

^§By thoracotomy (n = 4), CT-fine needle asp (n = 1), mediastinoscopy (n = 1).

^¶By CT-fine needle asp (n = 2), thoracotomy (n = 1), positron-emission tomography scan follow-up (n = 1).

^‖B cell lymphoma by thoracotomy (n = 1).
