Fibrosing mediastinitis mimicking as chronic pulmonary thromboembolism.

Fibrosing mediastinitis is an uncommon, benign, progressive disorder caused by proliferation of fibrous tissue within mediastinum resulting in encasement of vital mediastinal broncho-vascular structures. Due to its rarity and variable clinical presentation, it is often misdiagnosed. We are presenting a case of fibrosing mediastinitis in an Ethiopian origin young male presenting with pulmonary hypertension due to simultaneous occlusion of pulmonary vein and arteries, clinically misdiagnosed as chronic pulmonary thromboembolism.
