Objective: To compare features of pre-menarchal and post-menarchal patients with adnexal torsion.
Methods: We reviewed hospital records to note examination findings, laboratory work-up, imaging results, operative findings and course during hospital stay for 56 girls aged from 7 days to 17 years with adnexal torsion presenting between January, 2012 and December, 2020.
Results: 31 girls were pre-menarchal. Pain was the most common symptom. There were significant differences in the volume of the ovary visualized in ultrasound in amenorrheic and menstruating girls [median (IQR) 78234 (39600, 183600) mm3 vs 243432 (158661, 388800) mm3; P=0.004]. Pain was the most common symptom. Over the years, there was an increase in laparoscopic procedures, and efforts to preserve the ovary after the torsion.
Conclusions: The differential diagnosis in the case of abdominal pain should include adnexal torsion both in non-menstruating and menstruating girls.
