Summary

• A twisting of the ovary and/or fallopian tube on its vascular and ligamentous supports, blocking adequate blood flow to the ovary.
• Rapid diagnosis and intervention are necessary to preserve ovarian function.
• Most often seen in women of reproductive age between 20 and 40 years, but can occur during pregnancy, as well as in infants, children, adolescents, and post-menopausal women.
• Commonly presents with abdominal pain, nausea, vomiting, and an abdominal mass. High clinical suspicion is necessary. Clinical presentation is non-specific, with no absolute clinical profile.
• Transvaginal ultrasound with Doppler flow studies may show an enlarged ovary with absence of blood flow.
• Definitive diagnosis is surgical. Laparoscopic surgery with detorsion is the preferred treatment to preserve normal ovarian function and fertility.
