Sonography can identify abnormal pelvic masses in ovarian torsion, though the appearance is nonspecific. Preoperative ultrasound improved diagnosis and reduced unnecessary appendectomies.

Area of Science:

  • Radiology
  • Gynecology
  • Surgical Pathology

Background:

  • Ovarian torsion is a gynecologic emergency requiring prompt diagnosis.
  • Clinical presentation is often nonspecific, complicating preoperative assessment.
  • Sonography is a key imaging modality for evaluating suspected ovarian torsion.

Purpose of the Study:

  • To report the sonographic and clinical findings in patients with surgically confirmed ovarian torsion.
  • To assess the diagnostic utility of sonography in differentiating ovarian torsion from other conditions.
  • To evaluate the impact of preoperative sonography on surgical decision-making.

Main Methods:

  • Retrospective review of 13 patients with surgically proven ovarian torsion.
  • Analysis of sonographic features, including mass characteristics and location.

  • Correlation of sonographic findings with clinical presentation and surgical outcomes.

    • Main Results:

    • All patients demonstrated an abnormal pelvic mass on sonography.
    • The mass appearance was variable (solid to cystic) and often associated with underlying ovarian pathology (69%).
    • Mean mass diameter was 8 cm, frequently located in the midline (8/13).
    • Correct preoperative diagnosis was achieved in only 35% of patients due to nonspecific clinical findings.
    • Preoperative sonography decreased the rate of unnecessary appendectomies.

    Conclusions:

    • Sonography reliably detects pelvic masses in ovarian torsion but findings are nonspecific.
    • Associated ovarian pathology is common in ovarian torsion cases.
    • Despite nonspecific imaging, preoperative sonography aids in reducing misdiagnosis and unnecessary surgeries like appendectomy.
