A Case of Behcet's Syndrome with Superior Vena Cava Obstruction and Massive Pericardial Effusion

Behcet's syndrome has been known as multisystemic disease caused by nonspecific immune mediated vasculitis, but it's precise etiology is not yet identified. Among the various systemic manifestations, pericardial effusion is extremely rare, and pericardial tamponade caused by massive pericardial effusion in Behcet'sydrome has not been reported in the literature. We report a case of Behcet's syndrome manifested as SVC syndrome due to SVC and right atrial thrombus with massive pericardial effusion resulting cardiac tamponade with the review of the literature.
