If diagnostic tests show the brain is contused, what does this indicate?

• A. The brain has increased swelling.
• B. The brain is bruised.
• C. The brain has no injury.
• D. The brain is damaged due to infection.

Answer: (B)

A brain contusion means the brain tissue itself has been bruised from trauma. It’s a localized injury where tiny vessels are damaged and bleeding occurs within the brain substance. The key idea is that contusion = bruising of brain tissue. Swelling can accompany contusions, but the defining feature is the bruised tissue, not the absence of injury or infection. So this finding indicates the brain is bruised, not that there is no injury or an infection.
