title: Bilateral tubal ectopic pregnancy following intra uterine insemination (IUI): A case report.
abstract: BACKGROUND
  The incidence of ectopic pregnancy varies between 1.5-2% of all pregnancies. Bilateral tubal ectopic pregnancy is rare. It may occur in 1 per 200 000 pregnancies.
  
  
  METHODS
  This is a case report of 25 year-old woman who underwent intra uterine insemination (IUI), because of tubal factor infertility (unilateral). On the 30(th) day after the IUI she complained from pelvic pain and vaginal bleeding. Pelvic ultrasound showed bilateral tubal ectopic pregnancy with fluid in Douglas Pouch and empty uterine cavity. Exploratory laparotomy, left salpingectomy, and right salpingostomy were performed on the same day of admission.
  
  
  CONCLUSIONS
  The above case suggests that cases presenting with infertility and ectopic pregnancy should be followed very closely with β-hCG and or Trans Vaginal Sonography (TVS) to exclude double ectopic. So, as in this case, early diagnosis is essential for prevention of maternal morbidity and mortality.
