Ovarian torsion (OT) or adnexal torsion is an abnormal condition where an ovary twists on its attachment to other structures, such that blood flow is decreased.[3][4] Symptoms typically include pelvic pain on one side.[2][5] While classically the pain is sudden in onset, this is not always the case.[2] Other symptoms may include nausea.[2] Complications may include infection, bleeding, or infertility.[2][5]
Risk factors include ovarian cysts, ovarian enlargement, ovarian tumors, pregnancy, fertility treatment, and prior tubal ligation.[3][2][5] The diagnosis may be supported by an ultrasound done via the vagina or CT scan, but these do not completely rule out the diagnosis.[2] Surgery is the most accurate method of diagnosis.[2]
Treatment is by surgery to either untwist and fix the ovary in place or to remove it.[2][1] The ovary will often recover, even if the condition has been present for some time.[5] In those who have had a prior ovarian torsion, there is a 10% chance the other will also be affected.[4] The diagnosis is relatively rare, affecting about 6 per 100,000 women per year.[2] While it most commonly occurs in those of reproductive age, it can occur at any age.[2]
