An evaluation of the radiological signs of fetal death.
Radiological investigation is warranted in the antenatal patient only if the findings are likely to influence future management. The major radiological signs of fetal death are gas in the fetus, overlapping of the cranial bones and Deuel's halo sign. Gas patterns in the portal and umbilical vessels are unique and pathognomonic. Deuel's halo sign would be found more commonly if the correct radiographic view was employed. Spalding's sign is of no value before 20 weeks or if the fetal head is subjected to pressure. Hyperflexion of the fetus more often indicates intra-uterine growth retardation than death in utero.
