Pregnancy in a rudimentary horn of uterus is a form of ectopic pregnancy. Clinical manifestations will depend upon the development of rudimentary horn. Viable pregnancy in non-communicating rudimentary horn is very rare, as more than  80% cases of rudimentary horn pregnancy present in second trimester with rupture of the horn and is life threatening. Early diagnosis of rudimentary pregnancy is  required to avoid such complication. Sometimes, even modern ultrasonography scan cannot confirm the diagnosis of rudimentary horn pregnancy.  We report a case of successful pregnancy outcome at 34 weeks in a non communicating rudimentary horn.
