Adnexal torsion with paraovarian cysts in pediatric and adolescent populations: A retrospective study

Background: Determination of the clinical characteristics associated with adnexal torsion involving paraovarian cysts in pediatric and adolescent populations.Methods: Retrospective review of all cases of paraovarian cysts operated on in our department between 2007 and 2019. Demographic characteristics, clinical and sonographic findings were reviewed.Results: The cohort was composed of 39 pediatric and adolescent patients with an operative diagnosis of adnexal masses located in the paraovarian area. The patients were classified into two groups: 19 girls (48.7%) with a confirmed operative diagnosis of adnexal torsion and 20 girls (51.3%) without torsion. The preoperative diagnosis of adnexal torsion was correct in approximate to 70% of the cases. The mean BMI were similar in both groups. The preoperative sonographic detection rate of paraovarian cysts was also similar (11/19 [57.9%] vs. 14/20 [70.0%]; P = 0.514). The mean cyst diameter did not differ between groups, nor did the classification into cyst size groups (<= 50 mm, 51-99 mm and >= 100 mm).Conclusion: Adnexal torsion is a common complication diagnosed in girls undergoing surgery for paraovarian cysts, and is not associated with sonographic appearance or cyst diameter. In order to prevent torsion, surgical removal of paraovarian cysts should thus be considered in young girls undergoing surgery for paraovarian cysts.Type of study: Retrospective case series.
