What are brain abscesses?

ANSWER

Brain abscesses are areas of infection, including pus and inflamed tissue. They are not common, but they are life threatening. Brain abscesses often occur after an infection, usually in a nearby area, such as an ear, sinus, or dental infection. They can also appear after injury or surgery to the skull.
