The lithopedion was found floating in white, odorless pus, which made it semi-mobile and would explain Mathieu's claim that she could still feel the baby moving inside her.The lithopedion was extensively described and pictured in a published memoir by François Boyle, one of the doctors present.
Chatri became pregnant for the first time at 40, but never gave birth after breaking her water and going through labor pains.
She was bedridden for the next three years, during which she could notice a hard tumor on her lower abdomen, and complained of tiredness and abdominal pains for the rest of her life.
The patient largely recovered her health, but she continued to suppurate through the wound.
The patient had a failed pregnancy followed by a successful one, after which she fell sick and rapidly lost weight.
In 1880, German physician Friedrich Küchenmeister reviewed 47 cases of lithopedia from the medical literature and distinguished three subgroups: Lithokelyphos ("Stone Sheath"), where calcification occurs on the placental membrane and not the fetus; Lithotecnon ("Stone Child") or "true" lithopedion, where the fetus itself is calcified after entering the abdominal cavity, following the rupture of the placental and ovarian membranes; and Lithokelyphopedion ("Stone Sheath [and] Child"), where both fetus and sac are calcified.
Lithopedia can originate both as tubal and ovarian pregnancies, although tubal pregnancy cases are more common. The patient was pregnant in two separate occasions but never gave birth.
Christopher Bain, a travelling surgeon, practiced an incision and extracted "the skeleton of a male child".
She recovered fully and went on to have four more children.
At 37, she became pregnant, carried to full term and broke her water for the eleventh time, but she never gave birth despite the efforts of a physician.
She suffered from acute abdominal pain for two months and vaginal bleeding for five, and felt discomfort for the rest of her life.
Lithopedia may occur from 14 weeks gestation to full term. The lithopedia was carried for an average of twenty-two years, and in several cases, the women became pregnant a second time and gave birth to children without incident.
