We report a case of a triplet heterotopic pregnancy consisting of an intrauterine monozygous twin pregnancy and a tubal pregnancy after replacement of only two embryos in an in-vitro fertilization cycle with donor spermatozoa. This case demonstrates that sonographic demonstration of two intrauterine pregnancies after transfer of two embryos does not exclude the presence of an ectopic pregnancy. As both heterotopic pregnancy and spontaneous monozygotic twinning are more frequent after the use of assisted reproductive techniques, this combination, although extremely rare, must be kept in mind, especially in older patients with pre-existing tubal damage.
我们报告了一例三胎异位妊娠病例，该病例为体外受精周期中仅植入两个供体精子胚胎后，出现宫内单卵双胎妊娠和输卵管妊娠。此病例表明，在植入两个胚胎后超声显示两个宫内妊娠并不能排除异位妊娠的存在。由于辅助生殖技术使用后异位妊娠和自然单卵双胎更为常见，这种组合虽然极为罕见，但必须予以考虑，尤其是对于有输卵管损伤病史的老年患者。
