A baby girl was born “pregnant” with what was found to be twin fetuses in her abdomen.
According to a report in the latest issue of the Hong Kong Medical Journal, the girl was born in Queen Elizabeth Hospital in November 2010.
The fetuses were believed to be of eight to 10 weeks of gestation. Both had four limbs, a spine, rib cage, intestines and an anus. The “babies” were fertilized eggs that ended up being absorbed into her body as she developed.
The girl had to undergo surgery at 3-weeks-old to remove the fetuses.
The abnormality is called “fetus in fetu,” the Hong Kong Medical Journal’s report said.
It is an extremely rare condition, occurring in one in every 500,000 births in the world. Less than 200 cases have ever been reported.
The reason behind the abnormality is still unknown and the World Health Organization classifies it as a variant of mature teratoma, a type of cancer.
