[Pregnancy in rudimentary uterine horn: diagnostic and therapeutic difficulties]

Ectopic pregnancy in a rudimentary uterine horn is extremely uncommon. Implantation of one embryo in the uterine cavity and of another in a rudimentary uterine horn is an extremely uncommon form of twin pregnancy. The authors report three cases of pregnancies in a rudimentary uterine horn. One was associated to a heterotopic pregnancy in the other eutrophic horn. Through these three cases, they report the risks incurred and the difficulties of the assumption of responsibility of this type of pathology, on the diagnostic as well as therapeutic level. But generally underline the interest of echography especially endovaginale and the coelioscopy in the early diagnosis of this type of uterine malformation.
