The mortality and morbidity rates of non-tubal ectopic pregnancies with abdominal hemorrhaging are 7–8 times higher than those of tubal pregnancies. Diaphragmatic pregnancy is a rare non-tubal ectopic form, causing acute abdominal hemoperitoneum. Here, we present a case of a primary diaphragmatic ectopic pregnancy with hemorrhage that was immediately diagnosed and successfully managed with laparoscopic surgery. Rapid and accurate diagnosis using appropriate imaging modalities is critical for improving the prognosis of a child-bearing woman with an abdominal pregnancy.
