Prenatal Diagnosis and Successful Postnatal Surgical Management of Fetal Ovarian Cyst

Abstract

Fetal ovarian cysts are the most frequent abdominal tumor in newborns. It is the third cause of intra-abdominal cysts, after those of renal and gastrointestinal systems. Its presence can be suspected on ultrasound when a cystic-like tumor of regular structure located in the lower and lateral part of the abdomen, intestinal tract or urinary tract is observed in a female fetus with no anomalies. They present acute and long-term complications. The most frequent is adnexal torsion that presents diagnostic difficulties in the neonatal stage. Prenatal diagnosis is essential for the timely management. There are different therapeutic alternatives where minimally invasive and conservative surgery are important. The objective of the work is to demonstrate that the early diagnosis of fetal tumors intervenes in the successful outcome. We present the case of a 37-year-old primiparous patient, who had a soft-appearing tumor in the lower right part of the abdomen observed by ultrasound. This corresponded to a clearly identified fetal ovarian cyst and it was separated from the fetal bladder. The patient underwent cesarean section in which a female newborn was obtained. Two days later, the neonatal was minimal-access surgically treated successfully thanks to multidisciplinary management.
