Thymic metastasis. A 70-year-old woman with a thymic metastasis from breast cancer. a CT shows a 3.7-cm irregular shaped mass (arrow). b The mass shows slightly high intensity on T1WI (arrow). c The mass shows high intensity on fat-suppressed T2WI (arrow). d, e The mass shows slightly high intensity on DWI (arrow). ADC value is 2.02 × 10–3 mm2/s. f 18F-FDG PET shows slightly FDG uptake in the perivascular mass (SUVmax = 2.5) (arrow). CT, computed tomography; T1WI, T1-weighted imaging; T2WI, T2-weighted imaging; DWI, diffusion-weighted imaging; ADC, apparent diffusion coefficient; 18F-FDG PET, 18F-fluorodeoxyglucose positron emission tomography; SUVmax, maximum standardized uptake value
