Overview
MRI may be used in the diagnosis of mediastinitis. Findings on MRI suggestive of mediastinitis include mediastinal or hilar mass and calcifications of the central mass.[1] Pattern of involvement in mediastinitis is essentially similar to mediastinitis CT scan.[2] Findings on MRI suggestive of mediastinitis include heterogeneous but iso signals, mediastinal or hilar mass, and calcifications of the central mass.
MRI
Findings on MRI suggestive of mediastinitis include:[2][3][4]
- T1: typically heterogeneous but overall iso signal to muscle
- T2: variable with both high 3 and low 2-3 signal within the same lesion
- T1 C+ (Gd): may show heterogeneous enhancement
- Mediastinal or hilar mass
- Calcifications of the central mass
