Pathology.—Pneumopericardium is the presence of gas in the pericardial space. It usually has an iatrogenic, often surgical, origin in adults. Radiographs and CT scans.—Pneumopericardium is usually distinguishable from pneumomediastinum because the lucency (low attenuation) caused by air does not extend outside the pericardial sac (Fig 54). (See also pneumomediastinum.) [Fleischner Society]
