title: Spontaneous heterotopic pregnancy successfully treated via laproscopic surgery with subsequent viable intrauterine pregnancy: a case report.
abstract: BACKGROUND
  Heterotopic pregnancy (HP) refers to the presence of simultaneous pregnancies at two different sites of implantation, one intrauterine and the other extrauterine. The incidence of HP has increased in recent years secondary to a rise in the use of assisted reproductive technologies (ART).
  
  
  METHODS
  A 34-year-old woman, without risk factors for multiple pregnancies, presented with a spontaneous hypertopic pregnancy to a military facility. The ectopic pregnancy was successfully treated via laparoscopic surgery. She maintained a viable intrauterine pregnancy and was 32 weeks gestation with no complications at the time of submission.
  
  
  CONCLUSIONS
  This case highlights the importance of maintaining a wide differential in a patient who presents with elevated Beta-human Chorionic Gonadotropin Hormone (B-HCG) levels, which continue to rise, as well as signs and symptoms consistent with ectopic pregnancy.
  
  
  CONCLUSIONS
  Currently the rate of ART is rising; therefore, the expected cases of HP will likely continue to rise. At this time, there are no standard protocols for treatment and diagnosis of HP; this is an area that should be further researched in order to provide the best medical care for these women, the intrauterine pregnancy and future fertility.
