Testing results show there was a fetus in her abdomen, which was believed to have existed for between 27 and 40 years.
Le Quang Vinh, deputy director of the hospital, said the calcified fetus is causing acute pain and the patient needs surgery to remove the fetus.
However, doctors could not know whether the fetus lies inside or outside the patient’s uterus, and they need more clinical examinations to locate it.
The hospital is working with the Tu Du Obstetrics Hospital and National Obstetrics Hospital to deal with the case.
Sau said she went through menopause 27 years ago, her husband died 40 years ago, and her youngest son is 51 years old this year.
Doctors said lithopedion or “stone” fetus is a rare phenomenon which commonly occurs when a fetus dies during an abdominal pregnancy.
