Heterotopic pregnancy (simultaneous intrauterine and extrauterine pregnancy) is an extremely rare clinical phenomenon occurring approximately 1 in 30,000 pregnancies (1) or 1 in 2,000,000 live births (2). There have been 435 cases reported in the world literature up to 1956 (3). Simultaneous viability in heterotopic pregnancy is an even rarer event occurring in only 10.6% of cases (3).
