It Is Not Always an Ectopic or Heterotopic Pregnancy.

Uterine rupture is a life-threatening peripartum complication. Spontaneous uterine rupture in early pregnancy is very rare. The diagnosis of uterine rupture should be considered when a pregnant patient presents with an acute abdomen because its clinical signs in early pregnancy are non-specific and the differentiation with other acute abdominal emergencies is challenging. Here, we present a case of acute abdominal pain. The patient was a 14-week pregnant 39-year-old female (gravida 4, para 2+1) with a history of two lower-segment cesarean sections. Our preoperative diagnosis was either heterotopic pregnancy or acute abdomen. Emergency laparotomy confirmed the presence of a spontaneous uterine rupture.
