OBJECTIVE: To report a case of mifepristone-induced abortion in only one horn but a growing fetus in another horn for a twin pregnancy in a bicornuate uterus. DESIGN: Case report. SETTING: Department of Obstetrics and Gynecology, Chang Gung Memorial Hospital, Taiwan. PATIENT(S): A 31-year-old woman who conceived spontaneously presented with 37 days' gestation. INTERVENTION(S): Mifepristone 600 mg orally followed by misoprostol 400 mug orally 2 days later. MAIN OUTCOME MEASURE(S): Termination of pregnancy. RESULT(S): Induced abortion in only one horn but a growing fetus in another horn for a twin pregnancy in the bicornuate uterus detected by ultrasound. Surgical abortion with vacuum curettage was performed, and menstruation resumed 1 month later. CONCLUSION(S): As medical abortion with mifepristone and misoprostol becomes more prevalent, more studies are necessary to establish the dosage and regimens for multiple pregnancies associated with uterine anomalies.
