Figure 1: A sagittal gray scale image of the left ovary shows a 4.5 × 5.6 × 4.5 cm cystic mass with low-level-dependent echoes, consistent with internal hemorrhage. A smaller cyst is seen internally, measuring 1.0 cm in diameter. The findings were identical when compared to the prenatal ultrasound. Similar findings were seen on the parental ultrasound.
