[Uterine rupture of a cornual pregnancy: an obstetric emergency].

Cornual pregnancy is a rare type of ectopic pregnancy. Its diagnosis is challenging as the fetus usually appears as being inside the uterus on ultrasound scanning. Cornual pregnancy is more dangerous than other forms of ectopic pregnancy since a severe maternal hemorrhage can result during a cornual rupture. A case of a uterine rupture in a 14-week cornual pregnancy is reported.
