A Pictorial Review of Pelvic Pain-Beyond the Genitourinary System.

Abstract: Pelvic pain may be caused by disorders of the reproductive, urinary, or gastrointestinal systems. In the pediatric population, pelvic pain is often first evaluated with ultrasonography, with other imaging modalities reserved for further workup or specific indications. Radiologists must be aware of the findings associated with common pelvic emergencies to allow prompt diagnosis and prevention of life-threatening complications. Although the range of pelvic pathology is extensive, this pictorial review presents ultrasound examples of common nontraumatic causes of pelvic pain encountered in the pediatric population, with a brief discussion about multimodality imaging features.
