A baby girl was born "pregnant" with twin fetuses, researchers say. The girl, who was born at Queen Elizabeth Hospital in Hong Kong in 2010, was originally believed to have two tumors in her abdomen, according to a new report in the Hong Kong Medical Journal. But it turned out they were two fetuses instead. The fetuses were developed enough that they each had a spine, intestines, bones with bone marrow, "primitive" brain matter, an anus, a rib cage and an umbilical cord, the study reports. Of course, this isn't a case of Immaculate Conception. "Since it is impossible for the little girl to have conceived the pregnancy on her own, the fertilization of the twin fetuses, of course, belongs to her parents, which has gone to the wrong place," Dr. Yu Kai-man told the South China Morning Post.
