Fibrosing mediastinitis as a rare mechanism of pulmonary oedema in sarcoidosis To the Editors:Pulmonary oedema in sarcoidosis can usually be attributed to congestive heart failure or veno-occlusive disease. Here we report a rare case of pulmonary oedema, which was due to pulmonary vein stenosis secondary to fibrosing mediastinitis.

A case of sarcoidosis with iterative spontaneous increase and decrease of thoracic lymphadenopathy is described. No condition such as infectious disease, particular environmental exposure or medication could explain this unusual course of thoracic sarcoidosis.
