Adnexal torsion is the fifth most common gynecologic surgical emergency, requiring clinician and radiologist awareness. It involves the rotation of the ovarian tissue on its vascular pedicle leading to stromal edema, hemorrhagic infarction, and necrosis of the adnexal structures with the subsequent sequelae. Expedient diagnosis poses a difficult challenge because the clinical presentation is variable and often misleading. ⋯ Persistence of adnexal vascularization does not exclude torsion. In the pediatric age group, gray-scale ultrasound is the best modality of choice. Obtaining CT and/or MR images should not delay treatment in order to preserve ovarian viability.

Awareness of radiation risks from CT scans among patients and providers and obstacles for informed decision-making.
Using the study design from a prominent 2004 study, we aimed to reassess patient, provider, and radiologist awareness of CT radiation more than a decade later. ⋯ Patients and providers in 2015 appear to be more aware of radiation dose from CT than they were in 2004. Discussion of CT scan radiation exposure and associated risks only occurs sometimes and may actually occur less frequently than perceived by emergency providers.
