Post-mediastinitis pulmonary hypertension. Pulmonary artery stenosis in a case of fibrosing mediastinitis with pulmonary hypertension. Contrast-enhanced CT scan demonstrated at two successive levels (a, b), with a soft tissue attenuation mass diffusely infiltrating the mediastinum with encasement and narrowing of the pulmonary arteries (arrows). The stenosis of the right pulmonary artery is perfectly observed on the oblique 3D rendering view (c) (arrow). This mass had no significant metabolic uptake on 18F-FDG PET/CT (not shown). Note also the stenosed upper pulmonary veins
