Injury to one side that results from a blow to the opposite side (as a blow to the forehead causing damage to the back of the skull or rear part of the brain).

A contra coup injury refers to brain damage that occurs on the side opposite the point of direct impact.
A condition, known by the French term, where an impact on one side of the skull can result in brain damage on the opposite side due to transmitted force.
