RESUMO
Behcet's disease is a multisystemic disease, in which vascular involvement occurs in 7. 7-60% of patients. There are three forms of vascular involvement such as venous occlusion, arterial occlusion and arterial aneurysm. Venous lesions are more common than arterial lesions and the common sites of venous thrombosis are inferior vena cava, superior vena cava, and superficial or deep veins of extremities. Thrombosis of cerebral venous sinus is an infrequent complication of Behcet's disease and it seems to be rare that both deep vein thrombosis and cerebral venous sinus thrombosis occured at the same time. We experienced a case of Behcet's disease complicated with thromboses of left common femoral vein and right transverse sinus. A 29-year-old man presented with persistent dull nature headache, nausea, vomiting, blurred vision and left lower leg swelling. Duplex ultrasonography of lower extremity showed thrombus in the left common femoral vein. Magnetic resonance imaging of brain showed isodense signal intensity lesions in right transverse sinus on Tl weighted image. On magnetic resonance angiography, the right transverse, sigmoid sinus and right internal jugular vein were not visualized. The patient showed substantial improvement after treatment with steroid, cyclosporine A and anticoagulants.
