Answer

Adhesive mediastinopericarditis is a reaction that usually follows suppurative or caseous pericarditis, cardiac surgery, or irradiation. This condition is rarely caused by a simple fibrinous exudate. The pericardial potential space is obliterated, and adhesion of the external surface of the parietal layer to surrounding structures occurs. Clinically, systolic contraction of the ribcage and diaphragm and pulsus paradoxus may be observed. The increased workload may cause massive cardiac hypertrophy and dilatation, which can mimic an idiopathic cardiomyopathy.
