Superior Vena Cava Syndrome Without Thrombosis Found in Behcet's Disease

Behcet's disease is a rare multisystemic disorder whose main pathological defectis vasculitis, and superior vena cava (SVC) syndrome without thrombosis is a very rare manifestation of the disease. These authors encountered a case of SVC syndrome without thrombosis caused by Behcet's disease. A 33-year-old man visited the hospital for aggravated dyspnea without any related medical and familial history. He had a threeday history of abrupt swelling of the face, neck, and right arm. He suffered from recurrent oral ulcer, and there were acneiform nodules on his face as well as redness and swelling at the site of the intravenous injection. On the multi-detected computed tomography (CT) chest angiograms (chest angio MDCT), the SVC narrowed without thrombosis. Venogram was carried out, and percutaneous transluminal balloon angioplasty of the SVC stenotic site was performed. The following day, the swelling was found to have subsided. The details of the case are reported herein.
