Case Study of a Very Early Diagnosed and Successfully Treated Heterotopic Pregnancy

Abstract

Spontaneous heterotopic pregnancy (HP) is rare and defined as combination of intrauterine and ectopic embryo implantation in one pregnancy. Most cases present with acute abdominal pain with hemoperitoneum. During the early stages of pregnancy, a HP diagnosis is uncommon. In the following, we present a case report of spontaneous HP, which was diagnosed before tubal rupture, and discuss methods of early diagnosis. A 27-year-old woman was admitted to the clinic complaining of vaginal spotting. An ultrasonography revealed two corpus luteum cysts, as well as a six-week intrauterine pregnancy together with a right tubal pregnancy with no pelvic free fluid. A laparoscopic right salpingectomy was performed. The pregnancy continued with no complications and ended after a gestation period of 38 weeks and four days with a vaginal delivery. In conclusion, it could be beneficial to use a vaginal ultrasound for examining not only uterus but also both adnexal regions at the early pregnancy period.
