DOCTORS were stunned when they found a foetus trapped inside a 92-year-old's body for more than 70 years.
Doctors discovered the lifeless stone-like body in an X-ray on Estela Melendez who first became pregnant at 17.
The calcified foetus was found outside the Chilean woman's uterus - in a condition called lithopedion, commonly known as "stone baby".
Lithopedion is a rare phenomenon where the foetus develops outside the womb and dies.
It calcifies on the outside to protect the mother from infection because of the dead tissue.
Doctors told Melendez that the child apparently died in her seventh month of pregnancy.
They said it is unlikely they will remove the foetus because of the health risks of doing the procedure on someone her age.
Cases of "stone baby" are rare, but not unheard of.
A Colombian grandmother had a foetus removed in 2013 when doctors found that she was carrying her kid for 40 years.
