title: Mifepristone-induced abortion in one horn and a growing fetus in another horn in a patient with a twin pregnancy in a bicornuate uterus.
abstract: 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.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Department of Obstetrics and Gynecology, Chang Gung Memorial Hospital, Taiwan.
  
  
  METHODS
  A 31-year-old woman who conceived spontaneously presented with 37 days' gestation.
  
  
  METHODS
  Mifepristone 600 mg orally followed by misoprostol 400 mug orally 2 days later.
  
  
  METHODS
  Termination of pregnancy.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
