Baby Is Born 'Pregnant' With His Own Twin Brother Due to Rare Medical Condition

If you need proof that the human body is amazing, look no further than a recent birth in India. Doctors say a baby was born "pregnant" with his own twin brother. 


If it sounds like science fiction, it's not. Known as fetus in fetu, and sometimes dubbed as a "parasitic twin," this rare congenital anomaly pops up in the news every once in awhile, when a baby is born with parts of another baby inside them. It only occurs once in about every 500,000 births. 

Typically it's the baby's own twin who began to develop inside him or her.

Technically, it's not a pregnancy. Not only was this baby a biological boy who did not have a uterus, but typically the second baby or part of one is found in the retroperitoneal area of the body (i.e., inside a part of the abdomen). 

In the case out of India, doctors noted the in fetu twin during a prenatal scan, then removed it after the baby's birth. The mass had actual bones, arms, legs, and even a brain, although it was not a functional human being.

The mom's ob-gyn, Dr. Neena Nichlani, described the situation as a "case of monozygotic twin pregnancy sharing single placenta, where one fetus wraps itself around and envelops the other and robs the host of its nutrition." 

"It can be implanted in skull, abdomen, or tail bone of the host," Nichlani told the media. "Sometimes it can also lead to the death of the host because both get nutrition from a single cord." 

Fortunately, this little guy is going to be okay, although he'll have quite the story to tell for the rest of his life!
