In a case of lithopedion the fetus survived to 15 weeks' gestation. The mother had an infertility problem, and following tuboplasty she became pregnant and had an incomplete abortion, although no fetal parts or chorionic villi were found at dilatation and curettage. Five and one-half years later a second laparotomy was performed, and the lithopedion was discovered.
在一例石胎病例中，胎儿存活至妊娠15周。母亲存在不孕问题，输卵管成形术后怀孕并发生不完全流产，尽管刮宫时未发现胎儿组织或绒毛。五年半后进行了第二次剖腹手术，发现了石胎。
