Ovarian endometriotic cysts in a 36-year-old woman. The same patient as in Fig. 5. (a, b) Sagittal, (c) oblique axial and (d) oblique coronal T2-weighted images show bilateral endometriomas with intermediate to low signal intensity (white arrows). The ovaries are joined together behind the uterus (kissing ovaries). Note the low signal intensity in the declivous portion of the left cyst (“shading” sign, white arrowhead in c). On (e, f) sagittal and (g) oblique axial fat-suppressed T1-weighted images the cysts demonstrate high signal intensity (white arrows). (h) Photomicrograph (H&E 20X). Ovarian endometriotic cyst
