Isolated torsion of the utero‐ovarian ligament

KEY CLINICAL MESSAGE: Isolated utero‐ovarian torsion poses a challenge to diagnosing adnexal torsion, as it may not present with imaging findings. Clinicians with high suspicion for torsion but lack of evidence on ultrasonography should proceed to diagnostic laparoscopy. ABSTRACT: Adnexal torsion occurs when the ovary rotates around its supporting ligaments, the infundibulopelvic and utero‐ovarian (UO) ligaments, often causing disruption of blood supply. This pathology often presents with acute pelvic pain and is a gynecologic surgical emergency. Diagnosis is typically made with Doppler ultrasound, although dual blood supply to the ovary poses additional diagnostic challenges and sensitivity of this tool is debated. In this case study, we present a case of missed torsion due to isolated compromise of UO ligament.
