In general, characteristics that are favorable for spontaneous resolution include masses that are simple in nature by ultrasound and less than 5 cm to 6 cm in diameter.
For women with simple-appearing masses on ultrasound, reimaging can occur during the remainder of the pregnancy at the discretion of the physician or during the postpartum period. All women should be provided with torsion and rupture precautions during the pregnancy (Am J Obstet Gynecol. 2011 Aug;205[2]:97-102). For women with more concerning features on ultrasound, referral to a gynecologic oncologist is warranted. If the decision for surgical management is made, minimally invasive surgery should be strongly considered due to minimal maternal and perinatal morbidity.
