On MR images, a large, multiloculated right ovarian cystic mass, approximately 10 × 10 × 12 cm in size, was located at front of the uterus. a Axial T2-weighted image shows the multiloculated cystic lesion accompanied with thick septations. Fluid-fluid levels are demonstrated in several cystic components (arrows). The atrophic left ovary with few follicles is also detected (arrowhead). b Axial T1 weighted image shows intracystic high signal intensities suggesting intracystic hemorrhage (arrows). c On the contrast-enhanced axial fat-suppressed T1-weighted image, the septations demonstrated strong contrast enhancement similar to that of uterine myometrium. d Axial diffusion-weighted image demonstrates the septations having high signal intesnsities. e On sagittal T2 weighted image the uterus is normal size without endometrial thickening (arrow). There is a small amount of ascites which is limited to the pouch of Douglas and vesicouterine pouch (arrowheads)
