===== Pathology =====

A brain abscess is a focal area of [[necrosis]] starting in an area of [[cerebritis]] surrounded by a [[membrane]].

Brain [[abscess]]es are suppurative [[infection]]s of the [[brain parenchyma]] surrounded by a vascularized [[capsule]]. 

Cerebral abscesses result from pathogens growing within the brain parenchyma. Initial parenchymal infection is known as cerebritis, which may progress into a cerebral abscess. 

Cerebral infection is commonly divided into four stages with distinct imaging and histopathologic features:

early cerebritis (a focal infection without a capsule or pus formation,can resolve or develop into frank abscess)
late cerebritis

early abscess/encapsulation - may occur 10 days after infection

late abscess/encapsulation - may occur >14 days after infection.
