1. What is the originating pregnancy type?Abdominal pregnancy, a form of ectopic gestation occurring outside the uterus
2. What is the average gestation period carried?22 years, with documented cases exceeding 50 years
3. How does a lithopedion form?It forms when a pregnancy grows in the belly instead of the uterus. The baby dies because it doesn't get enough blood, and the body slowly adds calcium around it to make a hard shell.
4. Why can a lithopedion stay inside a woman for many years?The calcium shell protects the dead baby and keeps it from causing infection. Because of this, the stone baby can stay hidden inside the belly for decades, even after menopause.
