An urban dweller patient, 38 years old, came for an ultrasound scan of a mass of the right lower quadrant at the imaging department of the district hospital. She also suffered from fecal and air stasis. The ultrasound scan revealed dilated bowel loops and a mass of the right lower quadrant with a clear view of the fetus head whose parietal diameter measured 56 mm corresponding to a gestational age of 23 weeks and 2 days. The uterus was empty. The hypothesis of a mummified fetus was raised and plain abdominal film X-ray of frontal standing position was made. It showed air-fluid levels and small bowel mass of the right flank with a well individualized fetal head and two femoral bones. A surgery was required considering the signs of complications mainly a small bowel obstruction by compression. laparotomy performed 24 hours later confirmed the diagnosis of lithopedion in its lithokeliphos form. The situation subsequently became normal and the patient, received at the 45th day, was feeling well.
