We presented the case of 20-year-old gravid female who presented in the emergency department with abdominal pain and bleeding per vagina.The gestational age was 17 weeks 3 days. According to previous ultrasonography scan done elsewhere dated 05.07.2021, showed live intra uterine fetus of 11 weeks 5 days gestation in the cornua of left horn of the uterus. Beta HCG level was 4000 IU/L. Ultrasonography findings were suggestive of fetal demise with rupture of one of the rudimentary horn of uterus with an ectopic intra-abdominal pregnancy. Post operative findings correlated with ultrasound findings.
