  		Figure 1. Transverse ultrasound shows a well-defined homogeneous hyperechoic mass with through-transmission of sound, focal cysts (white arrows) in the periphery and a small amount of free fluid (black arrow).

  		Figure 2. (a) Axial T1 weighted MR image before and (b) coronal image after intravenous gadolinium shows a low signal intensity mass, which avidly enhances. Note that there is also some septal enhancement (black arrow). The second mass (white arrow) is seen extending into the left upper quadrant. (c) Sagittal T2 weighted MR image of the pelvis shows an heterogeneous intermediate-to-high signal intensity ovarian mass posterior to the uterus with high signal follicles (arrowheads) in the periphery and free fluid (asterisk) within the pouch of Douglas.

  		Figure 3. Contrast-enhanced axial CT image shows two masses (arrowheads), one in the pelvis (a) and the other in the left iliac fossa (b). The masses displace surrounding organs and free fluid is seen in the right flank. Of note there are small retroperitoneal lymph nodes (black arrow) in the left para-aortic region.
