Ovarian Torsion in Adolescents with and without ovarian mass: A Cross-sectional Study

The aim of this study was to compare the characteristics of adolescents with and without adnexal mass who were diagnosed with ovarian torsion (OT).

Retrospective cross-sectional study.

Gynecology Department at Tepecik Education and Reseach Hospital, Izmir, Turkey.

Adolescent girls who received surgery for OT between March 2012 and October 2020 in our institution.

The patients were divided into 2 groups according to the presence or absence of an ovarian mass and compared. Demographic and clinical characteristics, imaging findings, surgery, and pathology reports of the patients were obtained. Differences in initial symptoms, ultrasound findings, the diagnostic process, and the degree of torsion in patients with and without ovarian mass.

Seventy-six patients were diagnosed with OT. Of the 76 patients, 41/76 (53.9%) had an ovarian mass (OTwM), and 35/76 (46.1%) had no pathology (OTnP). The admission to surgery interval was longer in the OTnP group (P = .03). Ultrasound findings of ovarian edema and the appearance of free fluid were significant in the OTnP group (P = .001). The largest dimension of the nontorsion ovary in the OTnP group was greater than in the OTwM group (P = .03). In addition, it was found that torsion more than 360° was more common in the OTnP group than in the OTwM group (24/35, 68.5% vs 41/18, 43.9%; P = .03).

In symptomatic adolescents without an ovarian mass, the presence of follicle peripheralization suggesting ovarian edema on ultrasound and the presence of free fluid in the abdomen are important in terms of suspicion of torsion for clinicians. In addition, the degree of torsion was increased in these patients.
