Role of

different imaging modalities in the evaluation of normal and diseased thymus. MRI chest in a 45-year-old female patient shows a rather well-defined superior anterior mediastinal lobulated soft tissue lesion eliciting heterogenous low T1 (a) and mixed signal in T2WI signals (b), with areas of restricted diffusion in out-of-phase image (d) compared to in-phase (b, c) image. It elicits diffusion restriction (e, f) with ADC value = 0.8. Histopathological confirmation revealed terato-dermoid tumor
