Ultrasound images of a 31-year-old woman with a pathologically proven hemorrhagic cyst and a CA 125 level of 28 U/ml. A Transvaginal ultrasound revealed a 6.5-cm multilocular cyst with no solid component in the left adnexa. B Color Doppler ultrasound revealed no color flow (color score = 1). The lesion was categorized as IOTA SR B4 and B5 and O-RADS 3 based on the sonographic findings
