Example of bilateral ovarian lesion with a solid tissue with a type II dynamic enhancement curve (e) and type III dynamic enhancement curve (e). a Axial T2-weighted sequence without fat saturation and (b) Axial unenhanced T1-weighted water sequence show a mixed right cystic and solid lesion with (c) large enhancing solid tissue portion (d) with corresponding curve of the tissular component showing a type III curve (orange curve) (e) consistent with an O-RADS MRI 5 score. c Axial T2-weighted sequence without fat saturation and (f) DCE MRI T1-weighted sequence show a large left cystic lesion with solid tissue represented by papillary projections (arrow), corresponding to a type II curve (pink curve). Note the myometrium is represented by the yellow curve. The hypothesis of a low-grade serous ovarian cancer was made and later proven on histology
