Background: Corneal pregnancy is rare and difficult to detect in the early stages. Due to the abundant blood supply in this area, a rupture can result in massive internal bleeding, shock, and even death. Therefore, immediate surgery is necessary, and patients must replenish their blood volume as soon as possible to ensure blood supply to important organs. For those whose blood pressure cannot immediately rise, surgery should be performed while resisting shock to buy time.
Case summary: We present the case of a 34-year-old Chinese woman at 19 weeks of gestation who had a corneal pregnancy. No abnormalities were detected in the examinations in the first trimester. This patient was 19 weeks pregnant and sought medical advice due to sudden lower abdominal pain, syncope, and hemorrhagic shock. After rescue and treatment, she recovered and was discharged from the hospital, afterwards, the patient gave birth to a child 7 years later.
Conclusion: The early diagnosis of cornual pregnancy is mainly based on ultrasound. However, there is a high incidence of missed diagnosis and misdiagnosis of this disease. Patients may face serious and life-threatening conditions in case of the rupture of cornual pregnancy. This disease can be mainly treated by surgery.
