Objective: Abdominal pregnancy is a rare form of ectopic pregnancy with very high morbidity and mortality for both the mother and the fetus. Diagnosis and management can pose some difficulties especially in low-resource centers. The objective of this stady is to illustrate the different epidemiological, clinical and therapeutic data of abdominal pregnancy. Patient and observation: We present an additional case of primary omental pregnancy at 12 gestational weeks presenting with symptoms of hemoperitoneum and acute abdomen. Pregnancy status was confirmed after admission. Transvaginal ultrasound examination revealed a single viable fetus with a large amount of free peritoneal fluid, but no intrauterine sac or adnexal mass Laparotomy was done according to pre-operative diagnosis of ruptured tubal pregnancy. Bilateral tubes and ovaries were intact omental pregnancy was detected and partial omentectomy was performed. Conclusion: Early diagnostic of omental pregnancy is difficult but essential to reduce the high mortality.
