A 56-year-old postmenopausal female presented by abnormal vaginal bleeding. On TVS examination, there was an ill-defined endometrial polypoid soft-tissue mass of heterogeneous echogenicity measuring about 20 mm in maximum diameter. a, b Sagittal and axial T2 WIs show irregular endometrial soft-tissue mass with ill-defined margins displaying intermediate SI (red stars), distending, and filling the endometrial cavity with poor tumor-to-myometrium interface (blue arrows). The mass also extends to the cervix (yellow arrow). c Axial DWI with b value of 1000 s/mm2 shows high SI of the endometrial soft-tissue mass. d Axial DW-ADC map image shows low signal intensity of the endometrial soft-tissue mass. Mean DW-ADC value of the mass = 0.789 × 10−3 mm2/s. e, f Sagittal and axial DTI map images demonstrate values of DT-FA and DT-MD in multiple ROI. Mean DT-FA and DT-MD values of the endometrial mass = 0.148 and 0.497 × 10−3 mm2/s respectively. Diagnosis: pathologically proved endometrial clear cell carcinoma
