A 20-year-old woman, primigravida, with a last menstrual period 8 weeks ago, presented with lower abdominal pain for two days and vaginal bleeding for one day. The gynecological examination found vaginal bleeding, no enlargement in uterine size, and a painful mass 4 centimeters in diameter in the right adnexal region. The serum β-HCG level was 8200 mIU/mL. Transvaginal ultrasonography revealed no gestational sac in the uterine cavity, but there were two gestational sacs in the right fallopian tube (Figures).

Ectopic pregnancies account for 0.4% to 1.3% of all pregnancies.1 The presenting symptoms may be a delayed menstrual period and acute abdominal pain. Ectopic pregnancies are most commonly located in the fallopian tubes.2 With the development of ultrasonography, tubal ectopic pregnancies can be diagnosed earlier and with the appropriate treatment the patient can be protected from serious complications.3 In this case, an emergency laparotomy was done. The patient went home the second postoperative day.
