“…In 75% of such cases there is incomplete fusion of the mullerian ducts and this anomaly is associated with various degrees of rudimentary horns connected to a unicornuate uterus. As in our case, the majority of rudimentary horns contain a functional endometrial cavity without connection to the unicornuate uterus 1 5 6. There is a predominance of right-sided rudimentary horns which may be caused by the slightly advanced development of the left mullerian duct 1.…”

“…In asymptomatic women, the presence of a rudimentary horn is most frequently diagnosed during the evaluation of fertility 6. Due to the thin and poorly developed myometrium, the most significant threat is rupture of a pregnancy in a rudimentary horn; 80–90% of the horns rupture between 10 and 20 weeks of amenorrhoea 3 4 5.…”

A 33-year-old woman presented with an ectopic pregnancy without any complaints. Laparoscopy was performed since a tubal pregnancy was expected. However, both fallopian tubes appeared normal and it was not possible to differentiate accurately between a pregnancy in a noncommunicating horn and a pregnancy in a bicornuate uterus. We therefore performed MRI which showed a thin myometrium around the pregnancy. In order to differentiate between a communicating and a non-communicating uterine horn the authors performed a hysteroscopy. Since there was only one cervical os, and an entrance to the second uterine cavity was not seen along the cervical canal, it was concluded that this pregnancy was situated in a non-communicating rudimentary horn. The non-communicating uterine horn, with the pregnancy in situ, was completely removed. Since a pregnancy in a bicornuate uterus is viable in contrast to a pregnancy in a non-communicating horn, accurate diagnosis is important. BACKGROUND

“…Some authors have suggested that cornual pregnancy refers to an ectopic pregnancy in a noncommunicating horn of a unicornuate uterus, 15 and others propose that cornual pregnancy refers to an intrauterine pregnancy in a horn of a bicornuate uterus or the lateral half of a septate/ subseptate uterus 13 . In the recent literature, a cornual pregnancy has been considered to be a true ectopic pregnancy, 9 and its clinical course would be similar to that of an interstitial pregnancy 16 , 17 .…”

Interstitial, angular, and cornual pregnancies and intrauterine pregnancies in an anomalous uterus are separate entities, and the impact of each condition on obstetric outcomes is completely different. However, there is considerable confusion in understanding and managing the natural course of each condition due to a lack of uniform terminology. The single most important factor for differentiating these types of pregnancies is to make an early diagnosis. The differences between interstitial, angular, and cornual pregnancies on 2-dimensional (2D) sonography are subtle. Although magnetic resonance imaging can be used to differentiate these conditions, it is not preferred as the initial assessment tool because of its limited availability and cost-effectiveness. Three-dimensional (3D) sonography has the advantage of providing views of the uterus that cannot be obtained with conventional 2D sonography. We describe 3 cases of interstitial, angular, and intrauterine pregnancies in a septate uterus that were clearly differentiated by 3D sonography. We demonstrate the differences in diagnostic imaging findings and emphasize the importance of 3D sonography in differentiating these entities.

“…Generally the identification of uterine anomalies is difficult and will need well-trained personnel. Criteria for recognition have been listed by Mavrelos et al [23]. During an established pregnancy, ascertaining the exact type of mullerian anomaly is extremely challenging, with a definite diagnosis of the subclass being possible only outside pregnancy.…”

Misoprostol and termination of pregnancy: is there a need for ultrasound screening in a general population to assess the risk for adverse outcome in cases of uterine anomaly?

Purpose and methodsWe reviewed the existing literature on medical termination of pregnancy in cases of congenital uterine malformation. Is medical termination of pregnancy safe in the presence of a uterine anomaly? Can termination of pregnancy still be performed when information concerning the presence of congenital uterine malformation is not available?ResultsThe risk of adverse outcome, i.e. uterine rupture, was high in class 2 uterine anomalies, whereas the risks in classes 3–6 were negligible. However, the very low incidence of class 2 anomalies in pregnant women results in a calculated risk of uterine rupture in medical termination of pregnancy on the basis of this anomaly of 1 in 300,000 pregnancies. Ultrasound scanning is of limited diagnostic value to diagnose congenital uterine malformations.ConclusionsThe implications of uterine anomalies are not an argument in the discussion whether to use misoprostol for termination of pregnancy in developing countries with scarce diagnostics tools.
