Doctors in Bogota, Colombia removed a fetus from inside the abdomen of an 82-year-old woman.
They estimate it’s been there some 40 years. The woman wasn't aware of it.
She went to the hospital complaining of stomach pain.
Doctors said the phenomenon is rare, but occasionally a fetus does not develop in the uterus and will move into the abdomen, where the dead tissue then calcifies.
The woman has since had surgery to have the fetus removed.
