Premenarchal patients present differently: A twist on the typical patient presenting with ovarian torsion.

Background/purpose: The aim of this study was to characterize differences between pre- and postmenarchal females with ovarian torsion.

Methods: A single-center review was conducted of all nonneonatal pediatric patients with ovarian torsion from 2011 to 2018. Clinical data were compared between pre- and postmenarchal patients.

Results: One hundred and twenty-seven patients were identified, and 25% were premenarchal. Premenarchal patients were more likely to have a delay in diagnosis (38% vs 20%, p = 0.042), develop ovarian necrosis (34% vs 17%, p = 0.036), and present without an associated adnexal mass (44% vs 0%, p < 0.001). All patients without a mass (n = 14) were premenarchal and presented with ovarian asymmetry. Patients without an associated mass underwent oophoropexy in the majority of cases. There were no differences in postoperative complication or recurrence rates between groups.

Conclusion: Premenarchal females with ovarian torsion can present differently than females postmenarche and often have a delay in diagnosis. Premenarchal females are more likely to undergo torsion without an associated adnexal mass and are at higher risk for ovarian necrosis. Oophoropexy is an appropriate treatment in the absence of an adnexal mass. A high-index of suspicion for ovarian torsion should be maintained for premenarchal females presenting with abdominal pain and an otherwise negative workup.

Type Of Study: Retrospective comparative study.
