title: Discordance in Mayer-von Rokitansky-Küster-Hauser Syndrome noted in monozygotic twins.
abstract: BACKGROUND
  We report a case of monochorionic, monoamniotic female twins with discordant congenital reproductive tract anomalies.
  
  
  METHODS
  We present the case of a 17-year-old monochorionic-monoamniotic female twin with Mayer-von Rokitansky-Küster-Hauser Syndrome (MRKH) and her twin sister, who had with normal female reproductive system. Monozygosity is investigated by the complete history, physical, and imaging data, antenatal and birth reports of both the patient and her monozygotic twin sister. Examination of these documents proves monozygosity of the sisters, and imaging studies demonstrate MRKH in one twin and normal female genitalia in the other.
  
  
  CONCLUSIONS
  This case is presented as proof of MRKH discordance in monozygotic twins.
