Reported is the case of a 24-year-old female who presented to the Emergency Department complaining of lower abdominal pain and vaginal bleeding, whose initial transvaginal ultrasound was interpreted as showing a viable intrauterine pregnancy (IUP) of 8 weeks gestation. Repeat transvaginal ultrasound during a subsequent Emergency Department (ED) visit 3 days later revealed bilateral ectopic pregnancies of 6.5 weeks gestation. ED physicians should be familiar with the limitations of transvaginal sonography, and should be wary of early "intrauterine" pregnancies that are diagnosed ultrasonographically by inexperienced operators.
报告了一名24岁女性的病例，该女性因下腹痛和阴道出血前往急诊科就诊，其最初的经阴道超声检查结果被解读为显示一个妊娠8周的存活宫内妊娠（IUP）。3天后该女性再次前往急诊科就诊时进行的经阴道超声复查显示为双侧妊娠6.5周的异位妊娠。急诊科医生应熟悉经阴道超声检查的局限性，对于由经验不足的操作人员通过超声诊断的早期“宫内”妊娠应保持警惕。
