Pseudotumeur cardiaque révélant une maladie de Behçet

Abstract

Intracardiac thrombosis is a rare complication of Behçet’s disease (BD), which may manifest as intracardiac tumor. In half of cases, its detection precedes the diagnosis of MB. High mortality rates may be related to post-surgical complications and/or pulmonary arteries involvement. We report the case of a 29-year old young patient, with a previous history of bipolar aphthosis, who underwent surgery after the detection of right atrium and ventricle tumor. Anatomo-pathological examination showed thrombus and MB was diagnosed in the postoperative period. Patient’s evolution was favorable under medical treatment based on corticosteroids, colchicine and vitamin K antagonists (AVK). The detection of intracardiac mass in a young subject should suggest the diagnosis of cardiac thrombus and Behçet’s disease, even in the absence of ethnic or geographical risk factors.
