Pneumopericardium Leading to Cardiac Tamponade in a Patient with Lung Cancer

Cancer-Related Pneumopericardium: A Case Report and Literature Review

Pneumopericardium is a relatively rare entity mostly described in the literature as a result of causes such as penetrating/blunt trauma and iatrogenic causes during cardiothoracic procedures. We are presenting a case of pneumopericardium as a complication of progressed gastroesophageal junction tumor along with a literature review of all cancer-related pneumopericardium cases reported in the last decade. We present the case of a 65-year-old male with a past medical history significant for locally advanced gastroesophageal junction adenocarcinoma who presented to the hospital with complaints of shortness of breath and fever. A chest X-ray showed an intact esophageal stent along with radiolucency around the cardiac silhouette which suggested pneumopericardium. Computed tomography scan of the chest confirmed the presence of pneumopericardium in posterior pericardium with foci of gas above the esophageal stent likely to be communicating with the pericardium. An echocardiogram was obtained which showed no signs of tamponade. Given the advanced nature of the disease we applied a conservative management given that the pneumopericardium was deemed to be small with no tamponade. Goals of care were discussed with the patient and his family and the patient opted for comfort care measures. This case report prompted us to perform an extensive literature review of cancer-related pneumopericardium from 2008 to 2019. We found 11 cases where it was reported secondary to malignancies of different kinds. Our aim is to compile a review for clinicians to view varied presentations and better direct therapy dependent on the individual case and clinical presentation in patients with cancer-related pneumopericardium. Moreover, although pneumopericardium is rare, it should be considered in differential diagnosis in patients presenting with shortness of breath or chest pain especially with cancers involving the cardiothoracic region.

Cardiac Tamponade Due to Pneumopericardium After Liver Transplant

Pneumopericardium is a rare cause of cardiac tamponade, and it is an extremely rare complication of liver transplant. Here, we present a patient with cryptogenic liver cirrhosis who experienced cardiac tamponade secondary to a tension pneumopericardium during the postoperative course after liver transplant.

A case of bronchopericardial fistula with tension pneumopericardium closed successfully by transpericardial intervention: A novel procedure

A pneumopericardium is a collection of air or gas in the pericardial sac which may cause cardiac tamponade, known as tension pneumopericardium. Tension pneumopericardium is a rare and lethal presentation of bronchopericardial fistula. There are very few reports in the literature of patients surviving with this condition, although prompt diagnosis and early intervention are important. Treatment options are limited. We present a rare case of tension pneumopericardium with cardiogenic shock due to bronchopericardial fistula in a patient with bronchogenic carcinoma who was successfully treated with transpericardial intervention.
