Superior vena cava syndrome due to chronic granulomatous mediastinitis

We report a case of superior vena cava syndrome developing progressively over twenty years in a 48-year-old Venezuelan woman. The investigations revealed a locoregional etiology for the vena cava obstruction, namely a granulomatous mediastinitis probably secondary to histoplasmosis. We discuss the etiology, the clinical features, the natural course, and the therapy of chronic mediastinitis.
