Figure 1

Synchronic ovarian serous cystadenocarcinoma and endometrium adenocarcinoma (stage IC) in a 60-year-old woman. (a) Sagittal T2-WI image shows a unilocular cystic mass with solid mural nodules (black arrow) of heterogeneous hyperintensity. There is an intermediate signal intensity mass filling the endometrial cavity (white arrow). ((b) and (c)) DWI: show high signal intensity corresponding to mural nodules (black arrowhead) and an ill-defined slightly hyperintense mass in the endometrial area (white arrowhead). ((d) and (e)) ADC maps: depict low signal intensity in the solid mural nodules (black arrowhead), with an ADC value of 0.81 × 10−3 mm2/s, while the cystic component presents values of 1.3 × 10−3 mm2/s. ADC value within the endometrial mass 0.79 × 10−3 mm2/s (white arrowhead). ((f) and (g)): Postprocessed axial images, in which fusion between DWI and T2-WI is obtained. Low ADC areas are represented in red.
