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.
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 .
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.

Cladophialophora bantiana (C. bantiana) is a melanin producing mold known to cause brain abscesses in humans. [1] It is one of the most common causes of systemic phaeohyphomycosis in mammals. [2] Cladophialophora bantiana is a member of the ascomycota and has been isolated from soil samples from around the world. [3]
Cerebritis is the inflammation of the cerebrum, which performs a number of important functions, such as memory and speech.It is also defined as a purulent nonencapsulated parenchymal infection of the brain which is characterized by nonspecific features on CT scans (ill-defined low density area with peripheral enhancement) and cannot reliably be distinguished from neoplasms.
Lumbar puncture is contraindicated if there is a mass in the brain (tumor or abscess) or the intracranial pressure (ICP) is elevated, as it may lead to brain herniation. If someone is at risk for either a mass or raised ICP (recent head injury, a known immune system problem, localizing neurological signs, or evidence on examination of a raised ...
