Abstract

Background: Adnexal torsion has been described most frequently in women of childbearing age however; it is not uncommon in premenarchal girls or postmenopausal women (17.2% of cases). Torsion of the ovary may occur separately from torsion of the fallopian tube, but most commonly the two adnexal structures are affected together and are responsible for 2.7% of all gynaecologic emergencies. Mature cystic teratoma is the most common type of ovarian germ cell tumour and is usually unilateral but can be bilateral in 10-15% of cases. In 3.5% of such cases unilateral torsion has been reported. Bilateral torsion is very rare. We present a rare case of bilateral torsion of a dermoid cyst. Case presentation/methods: We present a case of bilateral torsion of Dermoid cyst in an 18-year-old nulligravida who was managed by detorsion and bilateral cystectomy at laparotomy at the Komfo Anokye Teaching Hospital. We reviewed the literature for similar cases. Outcomes: Histopathology confirmed bilateral mature cystic teratoma. The patient has been having regular menstrual cycles after the procedure. Conclusion: We demonstrate that prompt surgical intervention should be considered to salvage the ovaries in cases of large and dense ovarian cysts to prevent complications such as torsion.
