Craniopagus Parasiticus And The Unformed Conjoined Twin
Causes of Craniopagus Parasiticus Conjoined twins occur when the process that separates most identical (monozygotic) twins doesn’t result in a complete separation. This usually occurs eight to 12 days after conception. But if the split happens a few days later it may stop before it is complete. There is also a possibility of two embryos fusing together. Parasitic twins differ from conjoined twins in that one twin fails to develop fully, perhaps due to a degeneration of the umbilical cord....
