A 26-year-old man without history of Behcet’s syndrome was admitted to our department with a history of headache, fever, dyspnea, and weight loss. Transthoracic echocardiography and brain magnetic resonance imaging revealed a right atrial thrombus and sagital sinus thrombosis respectively. Surgery revealed the mass to be a thrombus. After 1 month of treatment with warfarin, he had experienced right atrial clot again. The von Willebrand factor antigen level was found to be elevated in blood examination. The large right atrial clot resected by second open heart surgery and medical treatment continued with cyclophosphamide, and corticosteroid, and thrombus did not reoccur in 6-month follow-up. To the best of our knowledge this is the first case of cerebral vein thrombosis associated with right atrial clot formation.
