Ballance's sign is dullness to percussion in the left flank LUQ and shifting dullness to percussion in the right flank seen with splenic rupture/hematoma.[1]
The dullness in the left flank is due to coagulated blood, the shifting dullness on the right due to fluid blood.
It is named for Charles Alfred Ballance, an English surgeon, 1856-1936.[2]
