Figure 5: Bilateral serous cystoadenoma. Axial T1- (a, white arrows) and T2-weighted images (b, arrows) demonstrate bilateral multicystic ovarian masses. The cystic loculi are small, multiple, separated by thin septa and characterized by homogeneous low signal intensity on T1 and high intensity on T2-weighted images. Within the left mass there is a posterior small papillary mural projection (b, white arrow). After contrast media administration, 3D fat-saturated T1-weighted Spoiled Gradient Echo image (c, arrow) demonstrate enhancement of the mural projection. This is a highly suspicious sign of malignancy. Histology reports left borderline ovarian serous cystoadenoma and right ovarian serous cystoadenoma.
