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
