Primary ovarian pregnancy is one of the rarest types of ectopic pregnancy where the gestational sac is implanted within the ovary and its incidence ranges from 1:6000 to 1:40 000 pregnancies. Its presentation often is difficult to distinguish from that of tubal ectopic pregnancy and hemorrhagic ovarian cyst. Spigelberg criteria are historically used for diagnoses which are based on surgical and histopathological observations. Management is surgical despite the advance in medical treatment. We present a rare case of ruptured primary ovarian ectopic pregnancy in which patient presented in advanced gestation without any history of amenorrhea.
