Primary retroperitoneal ectopic pregnancy

Abstract

Ectopic pregnancy accounts for 1.5%-2% of all pregnancies and is a common cause
of pregnancy-related mortality during the first trimester. The most common location
is the fallopian tube and less than 2% are abdominal pregnancies. Retroperitoneal
ectopic pregnancy is an extremely rare type with a rather complex pathogenesis.
This unusual location has a high risk of life-threatening complications. Early diagnosis
is difficult because of the inability to differentiate signs, symptoms, chorionic
gonadotropin concentrations, and imaging with ectopic pregnancies from unusual
locations, such as the retroperitoneum. In addition, it is necessary to be careful
with the diagnosis of these cases when the most common sites of appearance do
not present alterations. Treatment consists of removal of trophoblastic tissue by
laparotomy or laparoscopy. A case of primary retroperitoneal ectopic pregnancy is
presented.
