Unruptured term pregnancy with a live fetus with placenta percreta in a non-communicating rudimentary horn.

Pregnancy in a non-communicating rudimentary horn is rare and such a pregnancy culminating in the delivery of a live fetus is even rarer. Despite advances in ultrasonography, the accuracy of ultrasound in diagnosing rudimentary horn pregnancy at advanced gestation remains elusive. Confirmatory diagnosis is made only at laparotomy. We report a multigravidae who presented at 37 weeks with transverse lie oligoamnios and decreased perception of fetal movement since quickening. Laparotomy for placenta accreta suspected on ultrasound revealed non-communicating unruptured rudimentary horn pregnancy with a live fetus and placenta percreta. Successful extraction of a term live fetus weighing 2.7 kg with excision of the rudimentary horn was carried out.
