Uterine malformations very often result in poor pregnancy outcome. The incidence of uterine malformations in general population is estimated to be about 3-5% and 5-10% in women with poor reproductive outcome2. Fertility and evolution of pregnancy depends on the type of uterine anomaly. Many of them are asymptomatic but it is important to consider this diagnosis in recurrent miscarriages - early and late, preterm labors, malpresentations, intrauterine growth restrictions and menstrual disturbances like menorrhagia, dysmenorrhoea. Septate and arcuate uterus represent approximately 75% of malformations while bicornuate, didelphys and unicornuate comprise the remaining 25%. Cases of pregnancy in a bicornuate uterus are still of sufficient interest and rarity to justify being reported. Airoldi et al . reported that high-risk obstetric intervention did not significantly increase the fetal survival rate for uncorrected uterine anomalies5. We are reporting a case of bicornuate uterus with a successful pregnancy outcome diagnosed at 05 weeks gestation in 5th gravida by ultrasound examination.
