Heterotopic pregnancy is an increasingly common complication of assisted reproductive technology. Abdominal pregnancy is a rare and life-threatening form of ectopic pregnancy that can present as the extrauterine portion of a heterotopic pregnancy. We present the case of a cryopreservedthawed embryo transfer that resulted in a simultaneous intrauterine and abdominal pregnancy first recognized at 10 weeks gestation. Ultrasound-guided transvaginal injection of potassium chloride into the abdominal pregnancy resulted in asystole and spontaneous resorption of the ectopic fetus, while the intrauterine pregnancy continued and resulted in a liveborn vaginal delivery at full term. Selective embryo reduction using a non-surgical approach in a haemodynamically stable patient can therefore be considered in the management of heterotopic abdominal pregnancy if diagnosed relatively early.
