“…On the other hand, it remains unclear how separate implantation occurs, following multiple fertilization with multiple ovulations. In HAP cases with primary AP, two possibilities may account for the unusual pathogenesis based on the idea that the sperm, ovum, or zygote could migrate through the peritoneal cavity without losing its fertilization potential 6,30 . One possibility is that one of the embryos, fertilized in the tube, reversely migrates into the peritoneal cavity and becomes implanted on the peritoneal surface, while another one normally migrates to the uterine cavity.…”

An alternative scenario is that one of ova escapes from fimbria trapping, and then becomes fertilized by a sperm in the peritoneal cavity and thereafter becomes implanted on the peritoneal surface; however, whether fertilization occurs in the peritoneal cavity or not remains unclear.…”

We report the case of a 36‐year‐old woman with spontaneously conceived heterotopic pregnancy with abdominal pregnancy. She visited the hospital at 5 weeks and 4 days of gestation and transvaginal ultrasonography revealed a normal intrauterine pregnancy. Two days later, she was urgently transported to the hospital due to extreme abdominal pain. Emergent laparotomy was performed to investigate the cause of massive intraperitoneal bleeding, which was confirmed to have been due to an abdominal pregnancy that implanted on the vesicouterine pouch. The hematic mass, including chorionic villi, was successfully removed from the peritoneum. The subsequent course of the intrauterine pregnancy was uneventful and a healthy baby was born at term. To the best of our knowledge, this is an extremely rare case report of a spontaneously conceived heterotopic abdominal pregnancy, in which the intrauterine pregnancy showed a successful outcome despite the collapse of the abdominal pregnancy at a very early stage.
