Abstract: Abdominal pregnancy is rare in the clinic, and the uterine ligament pregnancy is more rare in the literatures. We reported a case of uterine ligament pregnancy, and the related literatures were reviewed. The uterine ligament pregnancy is often accompanied by amenorrhea, or without history of amenorrhea, vaginal bleeding and lower abdominal pain. Mass rupture may occur early, with hemorrhage and shock, even life-threatening. Timely diagnosis of this disease, to avoid misdiagnosis and missed diagnosis, is depended on the β-hCG test, color ultrasound, magnetic resonance imaging (MRI) examination and surgical exploration, etc. The differential diagnosis should include tubal pregnancy, ovarian tumor, intrauterine pregnancy and so on. Laparoscopy surgery is main treatment of abdominal pregnancy, which is better for exposing surgical field, removing completely the lesions and reducing bleed. How to treat the placenta is the key of the laparoscopy operation of the abdominal pregnancy at intermediate and advanced stage.
