Spontaneous pneumomediastinum mimicking acute pericarditis

Abstract

ST-segment changes may provide a clue to the presence of pneumopericardium accompanying SPM. These EKG changes associated with SPM are rare. The management in SPM with concurrent pneumopericardium is mainly supportive. We describe two SP cases with concomitant pneumopericardium that presented with a deceptive clinical spectrum, closely mimicking acute pericarditis.
