Tests revealed an inflammatory syndrome, hepatic cytolysis, neutrophilic leukocytosis, and increased troponin levels. Cardiac magnetic resonance imaging showed a small myocarditis but no tissue abnormality on the conduction pathways. In the absence of evidence-based infection and favorable evolution under broad spectrum antibiotherapy, an adult-onset Still's disease was suspected and corticosteroid therapy administered. Evolution was then impressively favorable, with a persistent sinus heart rhythm 3 days later. Learning objective Febrile conductive disorders occurring during a systemic disorder with negative infection and auto-immunity work-up should lead to consider an adult-onset Still's disease, which can be treated and cured, especially with steroids. Moreover, fever, polyarthritis, neutrophilic leukocytosis, pericarditis, and myocarditis should lead to consideration of adult-onset Still's disease. © 2019 Japanese College of Cardiology.

Multifocal thrombosis was probably due to the initial congenital deficiency of anticoagulants, accompanied by a decrease in antithrombin III and protein C, against the background of their critical consumption in cascade thrombosis, in
