Three distinct types can be identified: (i) lithokelyphos
in which only the membranes are calcified and form a hard sheath around the fetus; (ii) lithokylephopedion where both the membranes and fetus are calcified; and (iii) true lithopedion where the fetus is infiltrated with calcium salts and the membrane has undergone minimal calcification.
