Pregnancy in unicornuate uterus without rudimentary horn: a case report

A unicornuate uterus is associated with numerous obstetric and gynaecological complications such as infertility, endometriosis, miscarriage, malpresentations, and intrauterine growth restriction. Around 2.3-13% of Mullerian duct anomalies present as unicornuate uterus. Management of unicornuate uterus is still uncertain and it leads to poorer pregnancy outcome. We present here a case of 26-year-old primigravida who presented to us with 40-weeks pregnancy associated with breech presentation. She was taken for elective caesarean section and intra-operatively she was found to have unicornuate uterus without rudimentary horn. Unicornuate uterus is associated with poor pregnancy outcome but a successful pregnancy is possible. Usual presentation of patients with unicornuate uterus is near their menarche and they have higher than usual gynaecological complications. Pregnancies in unicornuate uterus are prone to intra uterine growth restriction hence serial ultrasound should be done for regular fetal growth monitoring.
