Cornual heterotopic pregnancy: a case report

INTRODUCTION Cornual heterotopic pregnancy is a very rare condition; its incidence remains unknown. We report a case of cornual heterotopic pregnancy managed by laparoscopy and guided methotrexate injection into the cornual sac. CASE PRESENTATION A cornual heterotopic pregnancy was diagnosed at 9 weeks of amenorrhoea in a 31-year-old healthy woman. Ultrasound examination showed a well-formed intrauterine gestation without detectable fetal heart pulsation, together with a gestational sac situated in the right cornual region. After uterine evacuation under ultrasound guidance, the diagnosis of cornual pregnancy was confirmed on laparoscopy followed by methotrexate injection into the cornual gestational sac. CONCLUSIONS Cornual heterotopic pregnancy is a very rare and potentially dangerous condition. Diagnosis of cornual pregnancy could be made on ultrasound examination in this patient. Laparoscopy was useful as an alternative in confirming the diagnosis and aided further treatment.
