title: Ovarian torsion in a premenarcheal girl: MRI findings.
abstract: Adnexal torsion is an uncommon cause of severe lower abdominal pain in women and is often difficult to distinguish from other acute abdominal conditions. However, adnexal torsion should be considered in premenarcheal girls admitted with acute abdominal pain and evidence of an ovarian mass. Accurate and early radiological diagnosis is mandatory immediately after onset of clinical symptoms in order to preserve the viability of the ovary. Ultrasound (US) is usually the first line examination performed in an emergency setting, but computed tomography (CT) and magnetic resonance imaging (MRI) can be useful in case of ambiguous US findings, especially in patients with sub-acute symptoms and a suspected adnexal mass. This case report describes the additional value of MRI in a premenarcheal girl with sub-acute right fossa pain.
