The heterotopic pregnancy occurs when the implantation of two or more fertilizel ovum are implanted simultaneously intra and extra uterine or both extra uterine. The fetal mortality rate is between 65% to 95% and the maternal mortality rate is less than 1%. The main risk factors are asisted reproduction techniques, pelvic infl ammatory disease, previous ectopic pregnancy and previous tubal surgery. In this study we describe one case of heterotopic pregnancy without risk factors, in a twenty two years old. She was 10. 3 weeks of gestation, with an acute pelvic pain. The ultrasound showed one incomplete intra uterine pregnancy and a left tubal pregnancy. The video laparoscopy and the pathology report confirmed the diagnosis. Three important aspects from this pathology are: the low incidence, the ultrasound as an important tool and the defi nite surgical treatment.
