Simply explained, a brain contusion is a bruise of the brain tissue. Just like bruises that occur on other parts of the body, a brain contusion is caused by small blood vessel leaks. Because they involve structural brain damage, contusions are more serious than concussions.
A bruise is a common skin injury that results in a discoloration of the skin. Blood from damaged blood cells deep beneath the skin collects near the surface of the skin, resulting in what we think of as a black and blue mark. People typically get bruises when they bump into something or when something bumps into them. 1  Bruises can occur in some people who exercise vigorously, such as athletes and weight lifters. These bruises result from microscopic tears in blood vessels under the skin.
