Abstract: A case of cornual pregnancy misdiagnosed as incomplete abortion in another hospital was analyzed retrospectively, and the literatures of cornual pregnancy were reviewed. The etiology of cornual pregnancy may be related to pelvic inflammatory disease, abnormal reproductive organs and other factors. However, it is still not clear. Early diagnosis of cornual pregnancy is difficult, and misdiagnosis and missed diagnosis are common. The cornual pregnancy should be alerted when there are incomplete abortion, expired abortion, induced abortion incomplete, dilation and curettage incomple. The ultrasound examination in early pregnancy can improve the accuracy of diagnosis. Compared with expectant therapy, drug conservative treatment and ultrasound-guided induced abortion, the minimally invasive surgery has a higher success rate and lower risk. It is understandably less invasive than laparotomy. Therefore, the minimally invasive surgery should be advised in the diagnosis and treatment of cornual pregnancy.
