During the past 20 years mediastinal emphysema has been recognized with increasing frequency and a large number of papers are now available in the medical literature bearing on its pathologic physiology and clinical manifestations.1, 2, 3, 4, 5 McGuire and Bean6 have credited Laennec with the original description of the peculiar bubbling, crackling and popping sounds now considered so characteristic. Müller,7 in 1888, described bubbling crepitations synchronous with the heart beat as indicative of pneumomediastinum.
Mediastinal emphysema is most often a complication of another disease or condition. Air can reach the mediastinum from perforation of the esophagus, trachea or bronchus.
