Pulmonary hypertension caused by fibrosing mediastinitis: A case report and literature review

This case underscores the importance of considering FM in the differential diagnosis of chronic unexplained hemoptysis, particularly when accompanied by mediastinal calcification, lobar collapse, and pulmonary hypertension. Early use of pulmonary artery CTA can aid in timely diagnosis, and endovascular stent placement represents a effective minimally invasive treatment option for selected cases of FM-induced pulmonary artery stenosis.
