Recurrent right atrial thrombosis due to Behçet disease

Behçet disease is a rare condition sometimes associated with chronic cardiac inflammation followed by myocardial dysfunction and vascular inflammation. We report a case of recurrent right atrial thrombus due to Behçet disease despite continued anticoagulation therapy. The thrombus disappeared after the initiation of immunosuppressive therapy. To avoid a progression to thrombus or cardiac dysfunction in this recurrent case, the early identification of cardiac involvement of Behçet disease using echocardiography and/or cardiac magnetic resonance imaging might be important. Combined immunosuppressive therapy with prednisone and cyclophosphamide might be needed to treat recurrent thrombosis due to Behçet disease.
