Diagnosis and management of a spontaneous heterotopic pregnancy: Rare case report

INTRODUCTION AND IMPORTANCE: Heterotopic pregnancy is the occurrence of pregnancies in at least two different implantation sites in the same time. The diagnosis of heterotopic pregnancy remains one of the greatest challenges of the gynecological-obstetrical emergencies. CASE PRESENTATION: We report a rare case of spontaneous heterotopic pregnancy of a 32-year-old woman, diagnosed with a heterotopic pregnancy by ultrasound and treated by laparotomy in emergency obstetrical department of Ibn Rochd University Hospital of Casablanca. CLINICAL DISCUSSION: The existence of intrauterine pregnancy does not exclude an ectopic pregnancy. The occurrence of a spontaneous heterotopic pregnancy without risk factors is a rare event, the clinical symptomatology is often related to a threatened or ongoing abortion, the diagnosis of heterotopic pregnancy is not made until the appearance of signs of hemoperitoneum secondary to a ruptured EP, hence the importance of a systematic ultrasound examination of the adnexa during first trimester ultrasound. The standard treatment is conservative surgery, preferably by laparoscopy. Laparotomy retains its indications especially in forms with hemorrhagic shock. With the aim of preserving intrauterine pregnancy while removing ectopic pregnancy. CONCLUSION: The diagnosis of heterotopic pregnancy should not be excluded by the discovery of a UGI in a spontaneous cycle. Diagnosis is often difficult and management should be initiated as soon as possible given the risk of maternal mortality.
