A year old Chinese girl who is to be operated soon was diagnosed with her twin in her womb.
When Kang Mengru abdomen was seen protruding day by day she was taken to hospital for ultrasound after which the doctors were amazed to find a baby in the womb the child’s twin brother.
Doctors say that the embryo was not caught in the womb and has found another place to grow.
Mengru will undergo a Cesarean delivery. Such cases "foetus in foetus” is very rare and can be found one in every 500,000 pregnancies.
so the twin didn't develop untill the twin's sperm was attached to her twin sister's egg?
No, that's not how twins work...
Identical twins occur when a fertilised egg splits in half. In the case of parasitic twins, when the embryos begin to develop, they DO NOT fully separate, with one being more dominant than the other in its growth (taking the majority of the nutrients to grow), hence the other being called the "parasite" and it it wholly depends on the dominant twin and incomplete in formation.
In the case of Kang Mengru, her "parasitic" twin lied within her persons, otherwise known as "foetus in foetu", and it usually ensues with the parasite becoming into a tumour-like growth which needs to be removed as it poses a threat to the otherwise "healthy" twin.
sometimes only half of it grows with the normal-growing fetus...n they end up having 4 legs...etc...(the egg didnt split all the way n the top half basically dissolves)
