title: Pneumopericardium as a rare complication after esophagopericardial fistula.
abstract: Pneumopericardium is a rare clinical entity which is often complicated by trauma. Pneumoperdicardium resulting after esophagopericardial fistula is much rarer. We present a case of pneumopericardium as the complication of esophagopericardial fistula in a 53-year-old man. After undergoing radiotherapy for 26 times, the patient got a fever and an unspecified thoracic pain. Echocardiography showed the rectilinear echoes in the pericardium. Chest computed tomography revealed pneumopericardium, pericardial effusion, recurrence of lung cancer, and pneumonia in right lower and left lung.
