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. Introduction Conjoined twinning is a rare phenomenon occurring in 1 in 50 000 to 100 000. However since 60 are stillborn or die shortly after the true incidence is around 1 in 200 000 live births 1 . A rarer form of conjoined twinning is the dicephalus parapagus twins discordant for anencephaly in which the laterally united babies have two heads in one trunk. One of the twins has no cranium or brain tissue but both have upper limbs and two lower limbs. Whereas the incidence of conjoined twinning in our country is unknown there have been previous reports from Nigeria 2 . We recently encountered live dicephalus parapagus conjoined twins discordant for anencephaly who survived for 9 hours after delivery. Case presentation 9-hour-old female conjoined twins with one torso and two heads were brought into the sick babies unit SBU by a 25-year-old Nigerian mother of the Ekoi tribe in Cross Rivers State who just had her first .
