We describe an adult patient who presented with purulent pericarditis in
whom two-dimensional transthoracic echocardiography demonstrated a
marked decrease in the area of the right ventricular wall together with
the overlying fibrin following intrapericardial administration of a
fibrinolytic agent. Documentation of this decrease by measurements
performed and illustrated on two-dimensional images have not been
reported previously in an adult patient with purulent pericarditis, to
the best of our knowledge.
