RESUMO
INTRODUCTION: Heterotopic pregnancies are rare. However, they are occurring with increasing frequency. Unfortunately, diagnosis is frequently delayed, with patients presenting in extremis. CASE REPORT: We present a case of a heterotopic pregnancy diagnosed by point-of-care ultrasound (POCUS) in a woman presenting with lower abdominal pain, who had a documented normal first trimester ultrasound the day prior to presentation. DISCUSSION: Given the increasing rates of heterotopic pregnancies, we can no longer be reassured by the presence of an intra-uterine pregnancy (IUP) in a patient with concerning signs and symptoms of a ruptured ectopic pregnancy. A thorough POCUS evaluation of the uterus and adnexa is essential for the diagnosis of heterotopic pregnancy in the emergency department. CONCLUSION: This case highlights the value POCUS brings to the emergency department evaluation of patients in early pregnancy.
