Prenatal Ovarian Cysts
Ovarian cysts in fetus and infants are usually follicular in nature and less than 2 cm in size. They are commonly diagnosed between the 28th and 39th wk. of gestation by sonography. Hypotheses on etiology are: (1) Excessive fetal gonadotropic activity, (2) enzymatic abnormalities of the theca interna, and (3) abnormal stimulation by the mother HCG. Obstetric management consists on observation and vaginal delivery. After birth, diagnostic assessment and management will depend on the size and sonographic characteristics of the cyst. Simple anechoic cysts, and those less than 5 cm in size can be observed for spontaneous resolution. Cyst with fluid debris, clot, septated or solid (complex nature), and larger than 5 cm should undergo surgical excision due to the higher incidence of torsion, perforation and hemorrhage associated to them. Percutaneous aspiration of large simple cysts with follow-up sonography is a well -accepted therapy, preserving surgery for recurrent or complicated cases. Surgical therapy is either cystectomy or oophorectomy that can result in loss of normal ovarian tissue.
