Imaging findings
Enlarged pulmonary artery with severe post-capillary pulmonary hypertension. Absence of discernible pulmonary veins on the left and a very small left pulmonary artery. A massive area of conglomerate nodal and fibrotic tissue is seen throughout the mediastinum, causing severe compression and obstruction of pulmonary veins.
Key takeaways
Fibrosing mediastinitis, typically a sequela of granulomatous infection, can lead to severe and progressive pulmonary venous obstruction. This results in profound pulmonary hypertension and can be a fatal condition due to the occlusion of critical structures.
