Ectopic pregnancy is a leading cause of maternal mortality. A high index of suspicion of an ectopic pregnancy must be borne in mind, especially when a woman of reproductive age presents to the emergency department with abdominal pain and a positive pregnancy test. An ectopic pregnancy can occur in unusual sites, particularly when assisted reproductive techniques have been used. Most ectopic pregnancies occur in the fallopian tube (so-called tubal pregnancies), but implantation can also occur in the uterine cornua, cervix, ovaries, and abdomen, including the retroperitoneum. We present only the second reported case of ovarian ectopic pregnancy in a 37-year-old woman following an in vitro fertilisation and embryo transfer for bilateral salpingectomies.
