Overview
Mediastinitis is the inflammation or infection of the mediastinum.[1] Although the pathogenesis of the infection remains unknown, radiographic, serologic, or histopathologic evidence of prior Histoplasma capsulatum infection, histoplasmosis, or chronic granulomatous disease is always observed. [2]
Pathophysiology
Gross Pathology
On gross pathology, characteristic findings of mediastinitis include:[3][4]
- White, fibrotic mass
- Distinct gap between adipose tissue
Microscopic Pathology
On microscopic histopathological analysis, characteristic findings of mediastinitis include:[3][4]
- Inflammation with granulated tissue
- Avascular and paucicellular fibrohyaline tissue
The progression to mediastinitis usually involves the infection by ''Histoplasma capsulatum'', but is not required for development of the disease.
