A case of immunoglobulin G4-related constrictive pericarditis

A 47-year-old man was admitted with a complaint of upper abdominal distension and shortness of breath. The constrictive pericarditis was diagnosed based on the transthoracic echocardiogram (TTE) and chest CT scan. Pathology revealed it is immunoglobulin (Ig) G4-related constrictive pericarditis. Likely, this is the first case of IgG4-related constrictive pericarditis reported in China.
