Hong Kong press shocked the public when on the news was reported that baby a baby was born pregnant with her own siblings.
However, this is not the first case something like this to happen, statistics show that 1 in every 500,000 births there is a case such as this, when a baby is born pregnant and this appearance is called fetus in fetu (or foetus in foetu). The reason how this condition is caused is still a mystery.
One of the theories is that the mass begins as a normal fetus but becomes enveloped inside its twin. The other is that the mass is a highly developed teratom.
Dr. Draion Burch from Pittsburgh who is gynecologist and obstetrician explains that in the early stages of the pregnancy some unordinary things can happen and the medical experts cannot understand why. His colleague Dr. Drai says: ”This is one of those medical mysteries.”
The World Health Organization considers this tiny fetus found within an infant to be a kind of teratoma, or tumor not a normally developing fetus.
