Moreover, they form as an inflammatory response to bacteria or fungal infections within the brain. This inflammatory response leads to a localization of infected brain cells, immune cells, and microorganisms within an area of the brain (Kumaret al. 2014). This area becomes encapsulated by an abscess wall, which is formed by adjacent cells to prevent further infection of neighboring structures. This results in the formation of an encapsulated, purulent (pus-filled) mass within the brain. While this inflammatory response can serve to protect the brain from further injury, it can also have significant negative consequences. If the abscess...
