BHCG was taken with levels of 12,962 mIU / mL and transvaginal ultrasound showing two rounded images of well-defined contours at the level of the right horn with a double halo sign with evidence of a yolk vesicle and two live embryos, a patient with a bichorial twin pregnancy was considered Right cornual and right cornuectomy was initially performed, however, since adequate control of hemostasis was not achieved, a total abdominal hysterectomy was performed without complications, the surgical specimen was sent to pathology in which decidua and mature villi were evidenced. third trimester in the myometrium without penetrating the serosa. Cornual ectopic pregnancy occurs in 2 to 4% of all ectopic pregnancies and has a global incidence of 1 in 2,500 to 5,000 live births, its diagnosis is of vital importance since, due to its location, cases of cornual pregnancies have been described up to the third trimester with an increased risk of uterine rupture up to 20% when they reach beyond the first trimester. However, it is important to highlight that the main complication of this entity is the rupture of the ectopic pregnancy, which is associated with bleeding and, if not controlled early, death of the patient.
