Dicephalus parapagus conjoined twins discordant for anencephaly: a case report

INTRODUCTION: Cases of conjoined twins occur so rarely that it is important to learn as much as possible from each case. CASE PRESENTATION: We present a case of 9-hour-old, female, Nigerian dicephalus parapagus conjoined twins discordant for anencephaly diagnosed only after the birth of the twins. The anencephalic twin was stillborn while the normal one died within 9 hours of birth from cardiopulmonary failure. CONCLUSION: Many congenital defects of interest can now be detected before birth. A severe lesion such as that found in our index case, which is incompatible with postnatal life, requires counselling. If detected early enough during a properly monitored antenatal care, it may indicate termination of pregnancy
