Recently produced reference curves for various ultrasound dimensions were used to retrospectively assess 67 pelvic ultrasound scans carried out at the initial presentation in girls with sexual precocity. At presentation the group with precocious puberty had significantly increased uterine lengths and ovarian volumes compared with the normal population, and a significantly increased fundal-cervical ratio. Ovarian volume was also significantly increased in therlarche and thelarche variant. The fundal-cervical ratio was significantly increased in thelarche variant. There was considerable overlap between individuals with sexual precocity and normal subjects. The ultrasound findings that best discriminated early or precocious puberty from other forms of sexual precocity were the presence of a midline endometrial echo, and a uterine length above the 97th centile for age. An entirely normal pelvic ultrasound at presentation did not rule out the possibility of precocious puberty.
最近生成的各种超声测量参考曲线被用于回顾性评估67例性早熟女童初诊时进行的盆腔超声扫描。初诊时，性早熟组与正常人群相比，子宫长度和卵巢体积显著增加，宫底-宫颈比值也显著增加。乳房早发育和乳房早发育变异型中卵巢体积也显著增加。乳房早发育变异型中宫底-宫颈比值显著增加。性早熟个体与正常受试者之间存在相当大的重叠。最能将真性性早熟或性早熟与其他形式的性早熟区分开来的超声表现是存在中线子宫内膜回声，以及子宫长度高于年龄的第97百分位数。初诊时盆腔超声完全正常并不能排除性早熟的可能性。
