Uncommon case of hydrosalpinx-induced adnexal torsion in a postmenopausal woman

Adnexal torsion is a twisting of the adnexa, including the ovary and/or the fallopian tube, around its own vascular axis. Most cases of adnexal torsion occur in women of reproductive age and only rarely in postmenopausal women. Here, we report a case of 58-year-old woman, postmenopausal for 6 years, who presented with acute lower abdominal pain. Ultrasound scan showed a right-sided, well-circumscribed, cystic mass measuring 50x57 mm with low level echoes. Doppler evaluation revealed no blood flow signals inside the mass. Abdominal exploration revealed right adnexal torsion. Salpingo-oophorectomy was done and histopathological examination revealed a twisted, gangrenous hydrosalpinx with no pathological lesion in the ovary. The patient was discharged on the fourth postoperative day. Although adnexal torsion in postmenopausal women is a rare event, it should not be ignored in those women who present with abdominal pain. A longer delay between admission and surgery may be attributed to the rarity and non-specific symptoms of the disease in this age group
