A 51-year-old postmenopausal female presented by menorrhagia and pelvic pain. A, B Sagittal and axial T2 WIs occupation of the endometrial cavity by a poorly defined large oval-shaped polypoidal soft-tissue mass displaying heterogeneous SI and infiltrating the uterine body (red arrow). The mass has foci of high SI due to necrosis (blue arrow). No cervical extension (red arrow). C Axial DWI with b value of 1000 s/mm2 high SI of the endometrial soft-tissue mass (yellow arrow). D Axial DW-ADC map image low signal intensity of the endometrial soft-tissue mass (red arrow). Mean DW-ADC value of the mass = 0.898 × 10−3mm2/s. Mean DW-ADC values at areas of intact and infiltrated myometrium = 1.104 and 0.912 × 10−3mm2/s, respectively. E, F Sagittal and axial DTI map images values of DT-FA and DT-MD in multiple ROI. Mean DT-FA and DT-MD values of the endometrial mass = 0.143 and 0.415 × 10−3mm2/s, respectively. Mean DT-FA and DT-MD values at areas of infiltrated myometrium = 0.146 and 0.478 × 10−3mm2/s, respectively. Mean DT-FA and DT-MD values at areas of intact myometrium = 0.389 and 1.252 × 10−3mm2/s, respectively. Diagnosis Pathologically proved endometrial stromal sarcoma
