Midtrimester heterotopic abdominal pregnancy diagnosed and managed with imaging guidance: A case report

BACKGROUND: An abdominal pregnancy coexisting with an intrauterine pregnancy is a rare variant of heterotopic pregnancy. CASE: An abdominal heterotopic pregnancy was diagnosed at 22 weeks' gestation. Magnetic resonance imaging, magnetic resonance angiography and sonography were performed to elucidate the anatomy. A multidisciplinary conference was held and management options were discussed. The patient elected to terminate the abdominal fetus. Selective embolization of the abdominal fetus was attempted but was unsuccessful. Intracardiac injection of potassium chloride was performed without incident. The intrauterine fetus was delivered at 36 weeks without complications. CONCLUSION: Abdominal heterotopic pregnancies pose unique management challenges, and close cooperation between obstetricians and radiologists is essential.
