title: Simultaneous bilateral tubal pregnancy following in-vitro fertilization and embryo transfer.
abstract: A case of simultaneous bilateral tubal pregnancy resulting from in-vitro fertilization and embryo transfer is presented. Repeated transvaginal ultrasound examinations confirmed an intrauterine sac but no fetus. A diagnosis of early missed abortion was incorrectly made and a curettage was performed. The pathological examination showed the presence of decidua and Arias-Stella phenomenon but no chorionic villi. Diagnostic laparoscopy and laparotomy performed 40 days after embryo transfer (eighth week of gestation), revealed bilateral tubal pregnancy. Bilateral salpingectomy was performed.
