... some people have a parasitic twin?
Is it really true that ...
I have read about an Indian man, who had an unborn twin in his stomach, undiscovered until the man was in surgery to relieve severe stomach pain. Can humans really have twins embedded in their bodies?
This rare condition is called foetus in
foetu and it really is a partially-formed twin, inside a person's body. The condition occurs in one in 500,000 babies. It's caused by an egg absorbing another egg at a critical point in the embryonic stage. Afterwards, the absorbed twin exists as a parasite, getting nutrition from its host’s blood. Often, the parasite dies within three months.
After death, the embryo stops developing, yet this unborn twin can weigh two kilos! It may have a skeleton, skin, organs, even small limbs, but never a brain. In over 90% of foetus in foetu cases, the twin is visible as a benign growth, and surgically removed.

An unborn twin is often hiding behind the peritoneum of its host, but it could also exist in the brain or chest.
