Overview
Findings on CT scan suggestive of mediastinitis include mediastinal or hilar mass, soft-tissue attenuation, calcifications of the central mass, tracheobronchial narrowing, and pulmonary infiltrates.[1][2][3]
Computed tomography
On CT scan, the appearance of mediastinitis can be variable and dependent on the pattern of involvement. Typically, the disease affects the middle mediastinum and may demonstrate:[1][2][3]
- Mediastinal or hilar mass
- Infiltrative region of soft-tissue attenuation which obliterates normal mediastinal fat planes and encases or invades adjacent structures
- Calcifications of the central mass or associated lymph nodes (especially if there has been preceding histoplasmosis)
- Tracheobronchial narrowing
- Pulmonary infiltrates
The following are a collection of radiological findings demonstrating the presence of fibrosing mediastinitis:
