An 82-year-old Colombian woman, who was rushed to hospital after complaining of abdominal pains, was found to be carrying a 40-year-old foetus inside her.
The woman is suffering from a rare case of lithopaedion or "stone baby", where the foetus does not develop in the uterus because it has moved elsewhere, the Daily Star reported.
Only one in 11,000 pregnancies develop into a "stone baby" and it is not unusual for women to be unaware of this as their bodies are shielded from the dead tissue.
