Avoiding the fatal misdiagnosis of pregnancy in a noncommunicating rudimentary horn using 3D transvaginal ultrasound

Abstract

Rudimentary horn pregnancies are an increasingly recognized complication of Mullerian duct anomalies. They can lead to uterine rupture with severe maternal morbidity and mortality. We present the case of a 28-year-old woman with a prior surgical diagnosis of bicornuate uterus who was diagnosed with a 7-week pregnancy in the left horn of a bicornuate uterus by 2D ultrasound. Further investigation with 3D ultrasound revealed that the pregnancy was within a noncommunicating rudimentary horn of a unicornuate uterus. These findings were confirmed at laparotomy. This case illustrates the importance and benefits of utilizing 3D ultrasound in diagnosing suspected Mullerian anomalies.

Imaging diagnosis of rudimentary horn pregnancy: a case report

“…(III) An intrauterine pregnancy in a bicornuate uterus, uterine cavity where the GS is located communicates with the cervical canal. If two-dimensional ultrasonography is not clear due to artifact or poor patient condition, three-dimensional ultrasonography is helpful ( 11 ). MRI could be performed to improve the accuracy of diagnosis of RHP ( 6 , 8 ).…”
