Spalding sign (fetal demise)

Last revised by Mostafa Elfeky on 28 Jun 2024

The Spalding sign refers to the overlapping of the fetal skull bones caused by collapse of the fetal brain. It usually appears a week or more after fetal death in utero. 

This finding was originally described by Alfred Baker Spalding (1874-1942), an American obstetrician 2, on abdominal radiographs and is indicative of fetal demise.
