An amazing discovery in Greece. A 9-year-old girl went to the hospital suffering from stomach pains. Doctors say she was actually carrying her embryonic twin in her somtach.

Doctors at Larissa General Hospital examined the girl and surgically removed a growth they later discovered was an embryo about six centimeters (more than two inches) long.

"They could see on the right side that her belly was swollen, but they couldn't suspect that this tumor would hide an embryo," hospital director Iakovos Brouskelis said.
