Recurrent Exudative Pericarditis in the Course of Adult-Onset Still’s Disease—Two Case Reports

Abstract

Exudative pericarditis is a disease of varied aetiology requiring inclusion of both infectious and non-infectious causes in its differential diagnosis. The possible diagnoses include adult-onset Still’s disease (AOSD), a rare systemic inflammatory disease of unknown aetiology. AOSD typically develops in patients between 16 and 35 years of age and is characterised by fever, arthralgia, transient salmon-coloured rash and other abnormalities including pharyngitis, serositis (particularly pleuritis and pericarditis) and laboratory abnormalities, such as elevated white blood cell count and elevated markers of inflammation. We report two cases of AOSD with recurrent exudative pericarditis.
