Lithopaedion (the petrified fruit - the fruit lost during prenatal development , obezvozhivanija. Depending on the stage of development of the dead fetus is exposed to different changes. The fruit, lost up to 12 weeks, mostly resolved. If the fetus died after 12 weeks, when he formed his skeleton, resorption is impossible. Only the absorption of amniotic fluid, and the fetus is maceration (see), at least - mummification (see). In the latter case, it shrinks, squeezed, formed by the so-called paper fetus. Even rarer is the deposition of lime salts in mummified tissues of the fetus - is petrification (the petrified) and formed lithopaedion.
The period of finding lithopaedion in the mother's body is different (from several weeks to several years). Long stay lithopaedion usually does not reflect the General condition of women.

Lithopaedion (from the Greek. lithos - stone and paid ion - child) - petrified (calcified) the fruit. Dead and remaining a long time in the body of the mother of the fetus with the already formed the skeleton can be osmawani, drying (mummification) with the subsequent accumulation of salts, lime - petrification, incorrectly called by some authors stiffening (this bone formation is not happening). Usually calcification of the fruit is the result of an ectopic pregnancy, but also described isolated cases L. in the uterine cavity.
Accepted classification for fossil fruits of Kuchenmeister: 1) lithokelyphos (gr. kelyphos - shell), in which the calcification have only fetal membranes, the fetus or modificeres, or materials; 2) lithokelyphopaedion at which the fluid is absorbed and the fruit is fused in whole or in part with shells, calcification begins with shell and gradually spread to adjacent parts of the fetus; this type of L. is the most common; 3) lithopaedion - calcification of the fetus, without shells, as it happens in secondary abdominal pregnancy. Atopiceski L. can be in the same place where the embryos.
Stay lithopaedion in the mother's body is impermanent. In the case described by Kuchenmeister, he is 57 years old. Microscopic examination of the structure of most organs (liver, kidneys, lungs, skin, mucous membranes, and others) will be quite noticeable; the brain and the blood turn into an unstructured, cholesterol-rich mass. Especially well preserved-pattern muscles. Lime salts are deposited in L. from the mother's blood. Stay L. in the mother often not accompanied by any specific symptoms; there are cases when women who had abdominal L. corresponding to full-term fetus, successfully proceeded new pregnancy and was normal delivery. In rare cases, the development of connective tissue adhesions around L. can lead to the phenomena of obstruction of the intestines.
