A rare complication of pericardiocentesis: Pneumopericardium.

Pneumopericardium is the presence of air in the pericardial sac. Pneumopericardium after pericardiocentesis has been rarely reported in the literature. In the present case, we report a patient who presented with tamponade physiology during COVID-19 and developed pneumopericardium after emergency pericardiocentesis. Immediate recognition and treatment are crucial and chest x-ray, thorax computerized tomography, and transthoracic echocardiography (TTE) are used for diagnosis.
