Polymicrobial purulent pericarditis and peritoneal effusion in an immunocompromised patient with <i>Staphylococcus aureus</i> bacteraemia: a case report

To the best of our knowledge, this is the first report of purulent pericarditis and purulent peritoneal effusion in the settings of <i>S. aureus</i> bacteraemia with an absent primary infection focus. Clinicians should be aware of treatment options for purulent pericarditis and consider intrapericardial fibrinolysis, especially in patients not suited for more invasive pericarditis treatment.
