Pericarditis and Pulmonary Artery Stenosis Due to an Extragonadal Non-seminomatous Germ Cell Tumor: Case Report and Review of the Literature

Abstract Background Chest pain is a common complaint in the Emergency Department that rarely can be attributed to anterior mediastinal masses. Objectives We review the differential diagnosis for anterior mediastinal masses and their potential consequences. Case Report An unusual case of chest pain in a young male patient is presented that is caused by an anterior mediastinal mass associated with pericarditis and right ventricular outflow obstruction. Conclusion Pericarditis and right ventricular outflow obstruction are potential complications of anterior mediastinal non-seminomatous germ cell tumors.
