AB0099 Adult onset still’s disease revelaled by pericardial tamponade and myocarditis

Background Pericardial tamponade and myocarditis are very seldom complication of adult onset Still’s disease and exceptionally revealed the disease. A18-year- old man was hospitalised for fever, polyartharalgia, dyspnea and thoracic pain. Chest radiograph demonstrated large cardiac sillouette. The electrocardiogram showed tachycardia and non specific diffuse ST-T changes. Echocardiography revealed a mild alteration of left ventricular function and circumferential pericardial effusion with diastolic collapse. A pericardiocentesis yielded 300 ml of sersanguinos fluid. The white blood cell count was 41200 with 96% neutophils. An extensive evaluation for infection was unrevealing and tests for antinuclear factors and rheumtoid factor were negative. Still’s disease was diagnosed. The patient was treated with prednisone 1 mg/kg/day and rapidly improved. Objectives Methods Results Conclusion
