A lithopedion (also spelled lithopaedion or lithopædion; from Ancient Greek: λίθος "stone" and Ancient Greek: παιδίον "small child, infant"), or stone baby, is a rare phenomenon which occurs most commonly when a fetus dies during an abdominal pregnancy,[1] is too large to be reabsorbed by the body, and calcifies on the outside as part of a foreign body reaction, shielding the mother's body from the dead tissue of the fetus and preventing infection.
