The term adnexal torsion encompasses torsion of an ovary, a Fallopian tube, or both. It is defined as partial or total torsion of the vascular pedicle that makes up the suspensory ligaments of the ovary (utero-ovarian and infundibulopelvic ligaments). Torsion obstructs lymph flow, resulting in ingurgitation and edema that, if untreated, will increase venous and lymphatic pressure, reducing arterial flow and leading to ischemia and infarction.
The diagnosis is challenging because the clinical manifestations of adnexal torsion are nonspecific and can simulate other urgent abdominopelvic conditions as well as other gynecological conditions that call for conservative management.
