The Heart's Halo: Caring for Pediatric Pneumopericardium

Pediatric pneumomediastinum and pneumopericardium (PPC) are rare complications, which can arise from various etiologies. We report a case of pediatric PPC secondary to an asthma exacerbation and discuss relevant diagnostic and management principles. Physicians must be aware of PPC and its implications due to the high mortality rate. PPC patients require close observation with continuous cardiorespiratory and telemetry monitoring, and providers experienced in the management of cardiac tamponade at a center capable of providing cardiothoracic surgical intervention. Time to resolution is multifactorial, but can be achieved promptly with supportive care and treatment of underlying condition.
