A Case of Heterotopic Pregnancy in a Natural Cycle / 대한산부인과학회잡지

ABSTRACT

Heterotopic pregnancy is the coexistency of intrauterine and extrauterine pregnancy. The incidence of heterotopic pregnancy is about 1 to 30,000 pregnancy in a natural cycle. However, the frequency of heterotopic pregnancy has steadily increased because of rising incidence of pelvic inflammatory disease, pelvic surgery and the development of ovulation induction and assisted reproduction. The clinical diagnosis of heterotopic pregnancy is difficult due to low incidence. Many of the cases are diagnosed by rupture of ectopic mass that makes serious complication to mother and fetus. We experienced a case of heterotopic pregnancy in a 32-year old woman who presented with acute abdominal pain in a natural cycle and report this case with a brief review of literature.
