A pelvic examination will typically reveal a single vagina and a single cervix. Investigations are usually prompted on the basis of reproductive problems. Helpful techniques to investigate the uterine structure are transvaginal ultrasonography and sonohysterography, hysterosalpingography, MRI, and hysteroscopy. More recently 3-D ultrasonography has been advocated as an excellent non-invasive method to evaluate uterine malformations. Rudimentary horn A<unk>  may be associated with a rudimentary horn on the opposite site. This horn may be communicating with the<unk> , and linked to the ispilateral tube. Occasionally a pregnancy may implant into such a horn setting up a dangerous situation as such pregnancy can lead to a potentially fatal uterine rupture. Surgical resection of the horn is indicated.
