Abstract

Ectopic pregnancy occurs in approximately 1.5 to 2.0% of pregnancies and accounts for 6% of all maternal deaths. Nearly all ectopic pregnancies are implanted in the fallopian tube. However, they may rarely occur within the retroperitoneal area in 1.3% of the ectopic pregnancy. Early diagnosis is difficult because it is not easy to differentiate symptoms of ectopic pregnancy in obturator fossa with in fallopian tube. Treatment is the removal of ectopic tissue through laparotomy or laparoscopy. A 26-year-old woman was diagnosed with left ectopic pregnancy and amenorrhea for 9+0 weeks and visited our hospital. A diagnosis of ectopic pregnancy in obturator fossa was made by laparoscopy, ectopic conceptus removal and the ligation of left hypogastric artery was performed. We report this case with a brief review of the literatures.
