Pericardial effusion--an uncommon complication of Salmonella enteritis.

A 62-year-old lady who was receiving corticosteroids for rheumatoid arthritis was admitted suffering from dehydration due to salmonella enteritis. Despite rehydration and appropriate chemotherapy she remained unwell and developed hypotension and elevation of her jugular venous pressure. Echocardiography and subsequent aspiration demonstrated a purulent pericardial effusion from which S typhimurium was cultured. Following aspiration and a change of antibiotic therapy, her condition improved dramatically.
