Clinical Features

The classic triad of symptoms in EP is abdominal pain with vaginal bleeding or spotting in a woman with amenorrhea. While frequently seen in cases of EP, the positive predictive value of this presentation is low, as it is more commonly seen in threatened or spontaneous abortion than in EP and may occur in nonpregnant women due to other causes. Many other presentations occur and range from sudden abdominal pain with life-threatening hypovolemic shock to an absence of symptoms with an EP discovered incidentally on ultrasound exam. To achieve the goal of early diagnosis in as many cases as possible, EP should be considered in all women of childbearing potential who present with abdominal or pelvic complaints or with unexplained signs or symptoms of hypovolemia.
