Abstract Rudimentary horn pregnancy is a rare site of ectopic pregnancy. Diagnosis of rudimentary horn pregnancy requires a high index of suspicion as it can be easily missed during routine ultrasound scan. Rupture of rudimentary horn pregnancy can lead to catastrophic intraperitoneal hemorrhage with consequent maternal morbidity and mortality. Here, we report a case of ruptured non-communicating rudimentary horn pregnancy at 21 weeks of gestation in a 19 years old nulliparous woman which was initially missed during ultrasound scan and misdiagnosed as a case of anemia with pregnancy. The patient was managed immediately with excision of the horn through urgent exploratory laparotomy. High index of suspicion and early referral from the discrete hospitals is needed before exact time is lost; thus reducing the morbidity and mortality of the pregnant women.
