Abstract

Ectopic pregnancy is an implantation of the fertilized ovum on a place except the endometrium. Most of the ectopic pregnancies are located at the fallopian tube. Only the 1.4% of ectopic pregnancies are abdominal pregnancies, of which only 15 cases of retroperitoneal pregnancies are reported all over the world. In this case, a 21-year-old woman presented with back pain and amenorrhrea for 5+2 weeks with no past history. During the laparoscopic operation, there was retroperitoneal hematoma which was located between right paracolic gutter and presacral area and there was no adnexal mass or free pelvic fluid to be found. We stopped the operation and performed computed tomography angiography, in which small peripheral enhanced cystic lesion in pericaval space and large amount of hematoma in perirenal space were revealed. We performed explo-lapratomy, and eliminated the gestational sac which was located between the inferior vena cava and ureter. We report very rare case of retroperitoneal ectopic pregnancy with brief review of literature.
