Chinese baby girl born 'pregnant' with babies
When the mainland Chinese baby girl was born in a Hong Kong hospital in 2010, a scan showed the shocking visual of twins in her abdomen.
This rare condition termed fetus in fetu, which has reportedly only been documented 200 times in history, came to light today when the Hong Kong Medical Journal released its findings.
According to the New York Daily News via the South China Morning Post, this is not as rare as you may think.
Doctors believe that this happens to one in 500,000 newborns.
The baby girl had absorbed her mum's other fertilised eggs when she was developing in her womb.
The "twins", who would have technically been her siblings should they have survived, were already starting to grow limbs, ribs, intestines, skin and had umbilical cords attached to a placenta.
Dr Yu Kai-man told the South China Morning Post: "Since it is impossible for the little girl to have conceived the pregnancy on her own, the fertilisation of the twin fetuses, of course, belongs to her parents."
The 8 to 10-week-old fetuses were removed.
