Doctors in Saudi Arabia were shocked when an examination of a one year-old baby revealed the impossible - the baby was pregnant. An x-ray confirmed a tiny body inside of the baby and, after a whirlwind session of tests and research, they concluded that they had happened upon one of the strangest and rarest human anomalies.
Called fetus in fetu, there have only been 51 confirmed cases in human history. The baby’s mother was originally pregnant with twins, but through some unknown reason, one fetus literally absorbed the other. The absorbed fetus survives (if you want to call it that) as a parasitic lump of tissue in the surviving twin. The absorbed fetus is actually little more than tissue that has not died and is no more of a lifeform than a tumor.
Doctors are currently consulting to try and find a way to separate the parasitic twin from its surviving sibling. (Source)(submitted by kaathynguyen)
