From: Role of diffusion weighted MR-imaging in the evaluation of malignant mediastinal lesions
Seminoma: 30-year-old male with an anterior (prevascular) mediastinal mass identified on CT. The patient clinically presented with dyspnea and chest pain. a Axial T1 WI, b axial T2 WI, c axial STIR WI, and d sagittal T2 WI show a large well-defined macro-lobulated anterior mediastinal mass displaying rather homogeneous intermediate T1, relatively bright T2 and bright STIR signal intensities. The mass shows restricted diffusion; with the predominant bright areas on the e DWI corresponding to dark areas on the f ADC map: ADCmean = 0.615 × 10−3 mm2/s and ADCmin = 0.494 × 10−3 mm2/s
