The occurrence of a pregnancy in case of uterine malformation is a potentially high risk obstetrical situation. We report the case of a pregnancy developed in a unicornuate uterus associated with a rudimentary non-communicating horn of 28 weeks of amenorrhea, with a history of uterine rupture during the previous pregnancy in a context of in-utero fetal death more a complete placenta previa. The uterine malformation of this patient was known and had been diagnosed incidentally during the cesarean section of the previous pregnancy (pregnancy which had then developed in the normal horn). This type of uterine malformation and the complications that may be associated with it are discussed as well as the principles allowing the prevention of these complications.
