Two near Miss Case of Undiagnosed Rudimentary Horn Pregnancy and Review of Literature

Rudimentary horn is a developmental anomaly of the uterus. Pregnancy in a rudimentary horn is rare, represents a form of ectopic gestation. The diagnosis of the rudimentary horn pregnancy and its rupture in a woman is very difficult. It can be missed in routine ultrasound scan. Pregnancy usually terminates by rupturing in second trimester in 90% cases. Cases of pregnancy pregnancy progressing to the third trimester resulted in a live birth after cesarean section has been documented. We report two near miss cases of undiagnosed rudimentary horn presented in our department. 1 st case presented to our department in shock with features of acute abdomen in a multigravida with history of caesarean section and the diagnosis was confirmed at laparotomy that revealed ruptured rudimentary horn pregnancy and excision of the accessory horn was done. 2 nd case presented with intrauterine fetal demise in a primigravida at 15 weeks period of gestation. After failure of medical induction, dilatation of curettage was attempted. For suspicion of uterine perforation laparotomy was done. Excision of rudimentary horn altogether with the dead fetus and repair of perforated uterus was performed.
