Mediastinal fibrosis is extremely rare in Behcet's disease. Case presentation We present ultrasound and computed tomography (CT scan) in a 26-year male with mediastinal fibrosis and superior vena cava (SVC) thrombosis, with thrombus in left internal jugular veins (IJV) associated with Behcet’s disease. Conclusion Behcet's disease can cause mediastinal fibrosis in rare cases. CT and MRI are efficient methods for detecting mediastinal fibrosis and superior vena cava thrombosis.
