Thrombosis of the ovarian vein is a rare complication which arises classically in the postpartum. We report a case of 24-year-old woman with a history of Behçet's disease, who presented with pelvic and thoracic pain, tachycardia, dyspnea and fever occurring 2 weeks after delivery. Computed tomography revealed an ascending thrombosis of the iliac and right ovarian veins complicated by bilateral pulmonary embolism. The patient responded well to the combination of anticoagulants and immunosuppressive agents. Behçet's disease should also be considered as an etiologic factor for ovarian vein thrombosis.
