A Displaced Mass in the Abdomen, Torsioned Ovary Cyst

Ovarian cysts are one of the most common pathologies in the infancy period. Approximately 15% of intraabdominal masses seen in this period are genital origined and one-third of these masses are ovarian cysts. The incidence of ovarian cysts has been reported as 1 in 2500 live births. The most common complications in ovarian cysts are torsion and bleeding. Fetal ovarian cysts usually regress spontaneously in complicated cysts; laparoscopic or open surgery can be applied. A female infant with a diagnosis of intraabdominal cystic mass, suspicion of duodenal atresia, and mesenteric cyst made based on a prenatal ultrasonographic imaging was hospitalized in the neonatal intensive care unit for examination and treatment. The abdominal ultrasonography revealed a cystic lesion in the lower left quadrant. The patient was evaluated with abdominal CT for detailed evaluation 1 day later and revealed a cystic lesion in the right upper quadrant. The displacement of the cystic mass conducted the differential diagnosis in favor of mesenteric cyst and ovarian torsion. Laparoscopic surgery was performed for examination and treatment. It was observed that the left ovary was torsioned and displaced. Ovarian cysts are the most frequently observed masses among prenatal cystic masses in female fetuses. It should be kept in mind that cystic masses detected in the prenatal period may often be ovarian cysts and that these cysts can be displaced in the abdomen while torsion, and a treatment plan should be determined according to the clinical findings of the patient.
