Second-trimester tubal pregnancy is rarely encountered and published cases are limited. There are no established sonographic criteria to differentiate it from abdominal pregnancy; however, differences in their medical management make this distinction important. We report a case of a 14-week 5-day tubal pregnancy that presented near rupture. Sonography demonstrated many overlapping features with abdominal pregnancy. In addition, the extrauterine gestational sac was rounded and well defined and the placenta was crescent-shaped. We propose that these sonographic features represent a second-trimester tubal pregnancy rather than an abdominal pregnancy.
孕中期输卵管妊娠很少见，已发表的病例有限。目前尚无既定的超声标准来将其与腹腔妊娠区分开来；然而，它们在治疗方法上的差异使得这种区分很重要。我们报告一例孕14周5天的输卵管妊娠病例，该病例在接近破裂时就诊。超声检查显示出许多与腹腔妊娠重叠的特征。此外，宫外妊娠囊呈圆形且边界清晰，胎盘呈新月形。我们认为这些超声特征代表孕中期输卵管妊娠而非腹腔妊娠。
