A 53-year-old postmenopausal female presented by abnormal vaginal bleeding. A, B Sagittal and axial T2 WIs irregular endometrial thickening which is occupied by a soft-tissue mass displaying intermediate SI (red arrow). No visible tumor breaching through the junctional zone (blue arrow). C Sagittal DWI with b value of 1000 s/mm² high signal intensity of the endometrial soft-tissue mass (red arrow). D Sagittal DW-ADC map image: low signal intensity of the endometrial soft-tissue mass (red arrow). Mean DW-ADC value = 0.939 × 10⁻³mm²/s. E, F Sagittal and axial DTI map images: values of DT-FA and DT-MD in multiple ROI along the endometrial mass. Mean DT-FA value = 0.401, and mean DT-MD value = 0.962 × 10⁻³mm²/s. Diagnosis Pathologically proved endometrioid adenocarcinoma G1
