Emergency sonographic examination of the pelvis was performed in 41 girls (mean age, 13 years old) with clinical suspicion of ovarian torsion. Sonographic features consistent with diffuse swelling of the ovarian parenchyma and follicular enlargement in the cortical zone were detected in eight patients and were considered highly suggestive for torsion of the ovary. Surgery revealed ovarian torsion in seven of these cases and hemorrhagic ovarian cyst in one case. A cystic or complex ovarian mass was detected by sonography in five additional cases, and ovarian torsion was included in the differential diagnosis. Surgery revealed ovarian torsion in four of these cases and hemorrhagic ovarian cyst in one. A 100% sonographic sensitivity for space-occupying disease of the ovary was obtained with a positive predictive value of 88% for the diagnosis of ovarian torsion. The specificity of the method was 93%. Sonography appears to be an excellent method to evaluate patients with suspected torsion of the ovary.
对41名临床怀疑卵巢扭转的女孩（平均年龄13岁）进行了骨盆急诊超声检查。在8名患者中检测到与卵巢实质弥漫性肿胀和皮质区卵泡增大一致的超声特征，这些特征被认为高度提示卵巢扭转。手术显示其中7例为卵巢扭转，1例为出血性卵巢囊肿。另外5例通过超声检测到囊性或复杂性卵巢肿块，鉴别诊断包括卵巢扭转。手术显示其中4例为卵巢扭转，1例为出血性卵巢囊肿。卵巢占位性疾病的超声敏感性为100%，诊断卵巢扭转的阳性预测值为88%。该方法的特异性为93%。超声似乎是评估疑似卵巢扭转患者的一种极好方法。
