title: Pericardial effusion presenting as an anterior mediastinal mass.
abstract: The authors present a case of pericardial effusion in a patient with previous cardiac surgery. Because the pericardium is opened and not reclosed during surgery, fluid can extend superior to the normal upper reflections of the pericardium and simulate an anterior mediastinal mass.
