EP occurs when the fertilized ovum implants anywhere except in the endometrium of the intrauterine cavity. Approximately 95 percent of EPs occur in the fallopian tube, with the ampulla being the most common location of implantation. Sites of implantation outside of the tube include uterine cornua, abdomen, ovary, and cervix. Cornual and abdominal ectopics may present late with profuse hemorrhage and probably represent the majority of pregnancies in which the patient dies before reaching the hospital. Cornual and cervical ectopics can be easily confused with a normal intrauterine pregnancy on the ultrasound examination. In addition, a cervical pregnancy may be confused with a nabothian cyst.
