Resumen

Ovarian cysts in the fetus are the tumors most frequently detected in the prenatal stage. They are diagnosed by ultrasound during the third trimester at the abdominal level as an anechoic, unilocular image, in which the sign of the ‘daughter cyst’ may be present. Diferential diagnosis must be made with other intra-abdominal cystic lesions. The size of the cyst, the ultrasound characteristics and the presence of symptoms or complications will be the determining factors for perinatal management, which includes conservative management, prenatal aspiration of the cyst and postnatal surgery. We report the case of a 30-week pregnant woman with a female fetus who presented an abdominal cyst dependent on an adnexum which during the course of her ultrasound controls showed an increase in size and a change in the ultrasound pattern. During the postnatal stage, surgical management via laparoscopy was required, with favorable evolution and follow-up by outpatient clinic without complications.
