Most of these cases are reported in reproductive age group. A case of a 10-year-old premenarchal girl is reported who presented with acute abdominal pain and vomiting. BothUltrasonography (USG) and MRI suggested right ovarian mass with torsion. Laparoscopic evaluation revealed an enlarged right ovary with torsion and contralateral agenesis of uterine tube and left ovary. Detortion of the ovary and an ovarian fixation to the ovarian pedicle was done. This is the first reported case of a premenarchal girl presenting with an acute abdomen due to adnexal torsion along with contralateral tubo-ovarian agenesis.<\/jats:p>","DOI":"10.1136\/bcr-2017-224157","type":"journal-article","created":{"date-parts":[[2018,5,7]],"date-time":"2018-05-07T09:24:02Z","timestamp":1525685042000},"page":"bcr-2017-224157","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Unilateral
