Fibrous Mediastinitis: A Late Manifestation of Mediastinal Histoplasmosis

Abstract

Fibrosing mediastinitis is an uncommon manifestation of histoplasmosis that occurs primarily in younger patients. Findings include tracheobronchial narrowing, compromise of the main pulmonary artery and veins, and circumferential narrowing of the esophagus. The initial chest radiograph is often diagnostic, although additional studies including tomography and angiography help clarify the extent and severity of the disease process.
