Abstract：
BACKGROUND: Diagnosis of ectopic pregnancy can be complicated by nonspecific laboratory and radiographic findings. The multiple alternative diagnoses must be weighed against each other based on the entire clinical presentation.
METHODS: We present a case of a 20-year-old woman who arrived to the Emergency Department (ED) with abdominal pain and ended up being transferred for an Obstetrics evaluation of a possible heterotopic pregnancy. Her radiology-performed ultrasound had revealed an \"intrauterine gestational sac\" along with an adnexal mass near the right ovary. The patient was not undergoing assisted-reproductive fertilization, nor did she have meaningful risk factors for heterotopic pregnancy. The patient was managed expectantly over the ensuing week to see whether the intrauterine fluid was a true gestational sac. After multiple repeat ED visits, the diagnosis of ectopic pregnancy was made. Ultimately, the patient elected for surgical management of her ectopic pregnancy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case offers a reminder of the subtleties of radiographic identification of intrauterine pregnancies and the ever-present need to \"clinically correlate.\"

摘要：
背景：非特异性实验室和影像学检查结果会使异位妊娠的诊断复杂化。多个替代诊断必须根据整个临床表现相互权衡。
方法：我们介绍了一例20岁女性因腹痛来到急诊科（ED），最终被转院进行可能异位妊娠的产科评估。她的放射学超声检查显示“子宫内妊娠囊”以及右卵巢附近的附件肿块。患者没有接受辅助生殖受精，她也没有异位妊娠的有意义的危险因素.在接下来的一周中，对患者进行了预期管理，以查看子宫内液体是否是真正的妊娠囊。多次重复ED访问后，诊断为异位妊娠。最终,患者选择手术治疗她的异位妊娠。为什么一个紧急医生应该意识到这一点？：这个案例提醒了放射学识别宫内妊娠的微妙之处，以及“临床相关”的需要。\"
