The lithopedion (Calcified abdominal pregnancy) is a rare phenomenon and there are less than 300 cases reported in the medical literature.In this case, a 35 year-old patient had her third pregnancy 8 years earlier without medical assistance since then she came to our hospital with low back pain. Complementary examinations (Abdominal X-ray, Ultrasonography and Color Doppler Ultrasonography) demonstrated an extra uterine abdominal about 25 - week pregnancy with calcified areas. Exploratory Laparatomy was performed, with extirpation of a well - conserved fetus with non calcified ovular membrane.
