Which medical term describes a bruise-like injury of the brain?

• A. Brain Injury
• B. Contusion
• C. Stroke
• D. Concussion

Answer: (D)

Bruising of brain tissue occurs when trauma damages brain cells and tiny vessels, producing localized bleeding and swelling. This physical injury to the brain tissue is called a contusion. A concussion, in contrast, is a functional disturbance from trauma that may alter brain function without a visible bruise on imaging. Strokes are caused by a disruption of blood supply or a bleed within the brain and have a different mechanism and imaging findings. Brain injury is a broad term that covers any injury to the brain, not specifically a bruise. So the term that describes a bruise-like injury of the brain is contusion.
