Spontaneous Synchronous Bilateral Ectopic Pregnancy

Background: The occurrence of simultaneous ectopic pregnancies in two extrauterine locations is rare, particularly in spontaneous pregnancies. Case: This article describes the case of a 32-year-old woman who presented with persistently elevated β-hCG levels after a salpingectomy for a left ectopic tubal pregnancy. Results: Follow-up elevated β-hCG levels led to the discovery of a simultaneous right tubal ectopic pregnancy. Conclusions: Bilateral ectopic pregnancy is rare but must be suspected when β-hCG is elevated after treatment of an ectopic pregnancy. β-hCG follow-up can be helpful, even if chorionic villi are present in the initial surgical specimen.
