Adnexal torsion is a common emergency room query in young girls and teenagers presenting with pelvic pain. It is a consequence of an underlying adnexal lesion or to anatomical laxity of the suspensory/anchoring ligaments. Clinical symptoms at presentation can be confusing and nonspecific, yet prompt diagnosis and surgical intervention are essential to save the adnexa. Radiology plays a crucial role in the diagnosis of adnexal torsion. Our exhibit will review and promote the rapid MRI as the first line, one-stop imaging in the diagnosis of adnexal torsion and other causes of pelvic pain. Some cases will be presented with initial ultrasound images and demonstrate how MRI increased the confidence in the diagnosis. All presented cases have pathology correlation and or operative reports and follow-up imaging. We will show various cases of ovarian and tubal torsions and their mimickers. In particular, we include torsions due to anatomical laxity of the suspensory ligaments, resulting from tubo-ovarian cysts and solid adnexal masses as well as cases of isolated tubal torsions.
