Doctors discover 50-year-old fetus inside woman's abdomen

Doctors in Chile discovered 50-year-old fetus inside a woman's abdomen. BBC reports the woman, who is said to be in her 90s, went to the


hospital after a nasty fall and that's where doctors learned via X-ray that she had the decades-old fetus inside.

The phenomenon is known as a lithopedion and occurs when a fetus dies during pregnancy and then becomes calcified outside the uterus, allowing it to stay in the body.

Doctors say they sent the woman home and do not plan on removing the fetus because operating on a patient her age may be too risky.
