BACKGROUND: @entity26370 is a condition in which intra- and extrauterine pregnancies occur at the same time. Spontaneous heterotopic pregnancy is a rare event, with incidences ranging from 1 in 30,000 pregnancies to as high as 1 in 6 pregnancies assisted by reproductive technology. CASE REPORT: A 34-year-old @entity1 presented with a 10-week history of @entity2588 , @entity2371 , and generally feeling unwell. Ultrasonography revealed a 10-week intrauterine viable pregnancy and free fluid in the abdominal cavity. Emergency laparotomy was performed and a @entity7207 was encountered on the right tube with hemoperitoneum. Salpingectomy was performed. Her intrauterine pregnancy was intact with positive fetal cardiac activity when she was discharged. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: @entity26370 should be kept in the differential diagnosis of any @entity1 with an intrauterine pregnancy presenting with @entity490 , abdominal tenderness, or free fluid in the abdominal cavity.    2015 Elsevier Inc.
