Doctors in China have found an "unborn twin" in the brain of a one-year-old child in China, according to a study published in a journal. The child presented problems with motor functions and had an enlarged head. Fetus-in-fetu is the medical term for the rare phenomenon, which occurs when twins become conjoined in utero, but only one continues to develop.
