A brain abscess is a localized collection of pus or infected material within the brain tissue.

see also Intracranial abscess.

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

Brain abscesses are suppurative infections 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.
