Q. A 20-year-old primigravida at 17 weeks gestation has been referred by her gynecologist to the emergency department for excessive vomiting and giddiness. She is not on any medication other than antenatal vitamins. Her temperature is 98.6°F (37°C), pulse is 94/min, blood pressure is 108/70 mmHg while sitting and 102/ 60 mm of Hg on standing, and respirations are 14/min. Physical examination shows a gravid uterus at the level of the umbilicus. A serum beta hCG level of 120,000 mIU/mL is noted. A pelvic ultrasound shows an absence of the fetus and the endometrial cavity is filled with vesicular echogenic material. Multiple multiseptated bilateral ovarian cysts measuring 4-5cm are noted. Which of the following option better applies to these ovarian cysts in this patient?
