Quisto do ovário fetal: a propósito de um caso clínico abordado por aspiração intra-uterina

With the widespread use of routine ultrasound during pregnancy, the incidence of fetal ovarian cysts detected in uterus has increased in the past decades. Small follicular or functional theca-lutein cysts are a common finding in fetal and neonatal ovaries and, after delivery, the decrease of hormonal stimulation may lead to spontaneous resolution. However, a high rate of complications has been referred, the most common being ovarian torsion, which may be seen during pregnancy or even in the neonatal period, with subsequent loss of the ovary. Prenatal management of fetal ovarian cysts remains controversial. The authors report a clinical case of a large ovarian cyst, detected by routine ultrasound examination at 30 weeks, associated with an increase in the amniotic fluid volume. The ultrasound re-evaluation showed an increase in the cyst's volume, which prompted the decision to perform an intrauterine aspiration at 34 weeks. Cytologic analysis of the fluid confirmed the diagnosis of an ovarian cyst. A healthy female infant was born at 40 weeks and the neonatal abdominal ultrasound confirmed the progressive regression of the cyst.
