Timely Identification of Pregnancy in Noncommunicating Horn of Unicornuate Uterus by Three-Dimensional Transvaginal Ultrasonography

Abstract

Pregnancy in the rudimentary horn of a unicornuate uterus is uncommon and needs to be diagnosed at early stages to avoid uterine rupture to avert the high morbidity and mortality. In this case report, we discussed the advantage of three-dimensional transvaginal ultrasonography (3D TV-USG) in assessing the early pregnancy in the noncommunicating rudimentary horn of uterus. A 23-year-old woman approached us for routine pregnancy scan. The location of 5-week pregnancy was confirmed in the right noncommunicating horn of a unicornuate uterus by 3D TV-USG. She has undergone laparohysteroscopy, and excision of a gravid rudimentary horn was done. After an interval of 6 months, the patient received fertility treatment and conceived consequently. Although magnetic resonance imaging (MRI) is an excellent way of diagnosing uterine anomalies, the procedure is expensive, time-consuming, and not widely available. 3D USG is less expensive and more readily accessible for early diagnosis of uterine anomalies, particularly in health-care centers where MRI is not readily available or affordable.

A case of rudimentary uterine horn pregnancy complicated with placental implantation in later stages of pregnancy

“…Imaging examination plays a significant role in the diagnosis of female genital tract malformation. Currently, in the opinion of most scholars, ultrasound is the preferred examination method for the diagnosis of rudimentary uterine horn ( 17 , 18 ). However, by virtue of multisequencing, multiparameters, and multi-dimensional imaging, MRI has higher soft tissue and spatial resolution, can clearly display the anatomical structure of uterus and vagina, as well as the external form and contour of the uterus.…”

“…Finally, 72 reports were selected for our analysis.

“…Especially when detecting NCRHP in the first trimester of pregnancy, this disease can be managed by minimally invasive laparoscopic surgeries. [ 10 21 27 31 33 41 43 45 46 47 48 49 50 51 52 53 54 55 ] In some cases, laparoscopic surgeries are performed even in the second trimester of gestation. [ 10 43 ] Magnetic resonance imaging (MRI) seems to be particularly important for performing a prompt and correct diagnosis before laparoscopic treatment.…”
