The diagnosis of ovarian torsion is challenging and relies mostly on morphologic findings. Occasionally, women or children with acute pelvic pain who have undergone an initial ultrasound (US) evaluation with results interpreted as negative for ovarian torsion will return with recurrent or increasing pain, prompting an US reevaluation. The flipped ovary sign refers to a demonstrable change in the orientation of the ovary on follow-up US examinations, recognized by changing positions of ovarian landmarks established by follicles, cysts, or masses. This sign is valuable for identifying ovarian torsion in these patients, even in the absence of classic morphologic or Doppler features of ovarian torsion.
卵巢扭转的诊断具有挑战性，主要依赖形态学表现。偶尔，患有急性盆腔疼痛的女性或儿童在初次接受超声（US）检查后，结果被解释为卵巢扭转阴性，但随后会因复发性疼痛或疼痛加剧而回来接受超声复查。翻转卵巢征是指在随访超声检查中卵巢方向出现可证实的变化，这可通过卵泡、囊肿或肿块所确定的卵巢标志位置的改变来识别。即使在没有卵巢扭转的典型形态学或多普勒特征的情况下，该征象对于识别这些患者的卵巢扭转也很有价值。
