BackgroundOvarian torsion is a rare but serious cause of pelvic pain in females. Making the diagnosis is important because misdiagnosis can lead to an ischemic ovary and subsequent infertility.ObjectiveAlthough all emergency physicians are aware of ovarian torsion, there are several myths regarding its epidemiology, diagnosis, and treatment. This article attempts to review some of these myths to improve emergency diagnosis and evaluation.DiscussionOvarian torsion is not an easy diagnosis to make and it is commonly missed. Signs and symptoms often mimic other disorders such as appendicitis, pyelonephritis, and nephrolithiasis. The diagnosis becomes more challenging in that torsion can occur in female patients of all ages, including infants and the elderly. Normal arterial blood flow on ultrasound does not rule out ovarian torsion and not every patient will have a mass on imaging or a palpable mass on examination. Patients may have symptoms for several hours or days, and thus, ovarian torsion may be present even with a longer duration of symptoms. Surgery is the definitive treatment and may still be effective after several hours of symptoms.ConclusionsAlthough ovarian torsion is a challenging diagnosis, understanding myths surrounding the disorder may help emergency physicians consider it in unusual populations. If there is any clinical concern for ovarian torsion, a gynecologic consult may be helpful, even if imaging findings are not conclusive. Surgery remains the standard method for definitive diagnosis and treatment.Copyright © 2016 Elsevier Inc. All rights reserved.
