1. Pathophysiology a. Pelvic anatomy/pathology b. Clinical presentation c. Risk factors 2. Spectrum of ultrasound findings a. Grey scale b. Color Doppler 3. Diagnosis of ovarian torsion on CT and MRI 4. Surgically proven cases: a. Spectrum of ovarian and vascular findings b. Intraovarian and extraovarian masses as lead points c. Mimics 5. Approach to imaging and pearls 6. Contrast enhanced ultrasound Summary Statement Evaluation of ovarian torsion is often a diagnostic dilemma for radiologists. Ultrasound is the imaging modality of choice, per the ACR Appropriateness Criteria; however, classic findings are not always present. CT and MRI may help with indeterminate cases, or may be the first study ordered, if other pathologies are expected. A multimodality approach is indicated for complicated cases, although the diagnosis of ovarian torsion can remain difficult to confirm. Contrast enhanced ultrasound may improve future diagnostic accuracy.
