Emergency caesarean section done and a pair of thoraco-omphalopagus twins delivered. Both babies died soon after birth. In the second case the conjoined twins were diagnosed prenatally at 20 weeks of gestationon in routine anomaly scan as thoraco-omphalopagus twin with fetuses were positioned face-to-face and fused from sternum to umbilicus. Fetuses were found to have separate hearts, a fused liver and separate upper and lower gastrointestinal tracts. Each twin had two normal appearing kidneys and a urinary bladder.
