Heterotopic pregnancy is a rare obstetrics phenomenon and carries significant maternal morbidity and mortality due to the risk of rupture of the ectopic pregnancy. Physicians tend to feel comfortable and relieved when an intrauterine gestation sac is seen. This results in an inadequate inspection of the adnexae and remaining structures during emergency bedside ultrasound despite a strong initial clinical suspicion of ectopic pregnancy. We present a case report of ruptured ectopic pregnancy and massive hemoperitoneum in a patient with heterotopic pregnancy. The diagnosis was done on bedside ultrasonography in a clinically unstable 32-year-old patient with a history of infertility. She presented with acute abdominal pain, body weakness, and amenorrhea. She underwent emergency laparotomy and salpingectomy. In our context where ultrasound is not readily available, practitioners carrying out salpingectomy for ruptured ectopic pregnancies should bear in mind the plausibleness of heterotopic pregnancy to properly handle the uterus.
