Brain abscess (or cerebral abscess) is an abscess within the brain tissue caused by inflammation and collection of infected material coming from local (ear infection, dental abscess, infection of paranasal sinuses, infection of the mastoid air cells of the temporal bone, epidural abscess) or remote (lung, heart, kidney etc.) infectious sources.
Amoebic brain abscess is an affliction caused by the anaerobic parasitic protist Entamoeba histolytica.It is extremely rare; the first case being reported in 1849. [2] Brain abscesses resulting from Entamoeba histolytica are difficult to diagnose and very few case reports suggest complete recovery even after the administration of appropriate treatment regimen.

The cyst wall is formed by proliferating capillaries, inflammatory cells, and gliosis (proliferating glial cells) in the case of brain and proliferating fibroblasts in the case of abscess cavities. Brain cells have a large amount of digestive enzymes (hydrolases). These enzymes cause the neural tissue to become soft and liquefy.
The final structure of the abscess is an abscess wall, or capsule, that is formed by the adjacent healthy cells in an attempt to keep the pus from infecting neighboring structures. However, such encapsulation tends to prevent immune cells from attacking bacteria in the pus, or from reaching the causative organism or foreign object.
Researchers have uncovered a recent, perplexing increase in brain infections and abscesses in kids and teens. These rare and life-threatening conditions can be complications of severe sinus ...
Infections of the central nervous system (CNS) consist of infections primarily of the brain and spinal cord. They include mostly viral infections , less commonly bacterial infections , fungal infections , prion diseases and protozoan infections .
The danger triangle of the face consists of the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla. [1] [2]: 345–346 Due to the special nature of the blood supply to the human nose and surrounding area, it is possible for retrograde infection from the nasal area to spread to the brain, causing cavernous sinus thrombosis, meningitis, or brain abscess.
