Multidetector computed tomography detection of bronchial diverticula.

Bronchial diverticula are associated with chronic obstructive pulmonary disease. With newer scanners, small structures such as these air-filled diverticula will be visible and could be mistaken for pneumomediastinum. We present a case in which retrospectively reconstructed thin-section computed tomography clearly depicted the presence of multiple bronchial diverticula enabling the diagnosis to be made with certainty.
