Fibrosing mediastinitis is a rare chronic fibrotic disease of the mediastinum. Fibrous tissue proliferation compresses the pulmonary veins, causing stenosis, obstructing pulmonary circulation reflux, leading to pulmonary congestion and pulmonary hypertension, with symptoms such as dyspnea and hemoptysis. Diagnosis relies on contrast-enhanced chest CT and pulmonary angiography. Treatment is mainly based on drugs to inhibit fibrosis, interventional procedures or surgery to relieve obstruction. The prognosis is closely related to the lesion scope and intervention timing.
