A Greek girl carried her twin for nine years. According to an Associated Press article, the young lady had stomach pains and a swollen belly so doctors went in to remove what they thought was a tumor. It turned out to be the child's embryonic twin, which was over two inches long. It said:
Andreas Markou, head of the hospital's pediatric department, said the embryo was a formed fetus with a head, hair, and eyes, but no brain or umbilical cord.
The doctor also said that cases where one twin absorbs the other while in the womb occur in one in 500,000 live births. The parents of the girl who has recovered did not want her identity released to the public.
