Air bronchograms and pseudocavitations (↑) are often visible in adenocarcinomas (bronchoalveolar carcinomas) and seldom occur in benign lung lesions. Air bronchograms can be also found in pneumonias, round atelectases, inside conglomerate masses in silicosis, and sarcoidosis. Fine lucencies against a neoplasm represent cystic sites filled with air (pseudocavitations).
