Abstract

Background: Heterotopic pregnancy (HP) is a rare condition where at least two pregnancies are present simultaneously at different implantation sites and one of them located in the uterine cavity. Its prevalence varies from 1 to 30 000 in a natural cycle to around 1 in 100 in an assisted one.
Case presentations: In the current study, we presented four cases of first trimester heterotopic pregnancy diagnosed by ultrasound (US).
Conclusion: However, heterotopic is a rare condition, any pregnant woman presenting with alarming abdominal pain and adnexal abnormality; heterotopic pregnancy should be among the differential diagnosis possibilities. The patient should be thoroughly investigated using 3D ultrasound if needed, to exclude this rare diagnosis and allow on-time proper management.
