Lithopedion

Lithopedion

Lithopedion (also known as Stone Baby) is a rare phenomenon which occurs most commonly when a fetus dies during an ectopic pregnancy, is too large to be reabsorbed by the body, and calcifies on the outside, shielding the mother's body from the dead tissue of the baby and preventing infection.

Causes

The primary cause of a lithopedion is an ectopic pregnancy, specifically one which occurs in the abdomen. Other causes can include a fetus developing in the ovary or in other locations in the abdomen.

Symptoms

Symptoms of a lithopedion can include abdominal pain, nausea, vomiting, and weight loss. However, in many cases, the condition may remain asymptomatic for many years.

Diagnosis

Diagnosis of a lithopedion is usually made through a combination of ultrasound, CT scan, and MRI. These imaging tests can show the presence of a calcified mass in the abdomen.

Treatment

Treatment of a lithopedion often involves surgery to remove the calcified fetus. In some cases, if the patient is asymptomatic and surgery would pose more risk than benefit, the lithopedion may be left in place.

Prognosis

The prognosis for a woman with a lithopedion is generally good, especially if the condition is diagnosed and treated early. However, if left untreated, complications such as infection, infertility, and bowel obstruction can occur.
