Brain abscess (or cerebral abscess) is an abscess 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, within the brain tissue.

Description. Caused by reactivation of T. gondii in immunocompromised individuals; Most common neurological disorder associated with AIDS (considered an AIDS-defining condition) Cerebral abscesses represent focal areas of infection within brain parenchyma, usually containing pus and having a thick capsule. They typically have enhancing walls and can mimic a number of other significant pathologies. Perinephric abscess is insidious in onset, with nonspecific symptoms that include flank or abdominal pain, fever, chills, and dysuria.

These adaptations include hypertrophy (enlargement of individual cells), hyperplasia (increase in cell number), atrophy (reduction in size and cell number), metaplasia (transformation from one type of epithelium to another), and dysplasia (disordered growth of cells). Cerebral edema is a potentially life threatening complication of severely decreased sodium ion concentration in the blood (hyponatremia). Ionic brain edema can also occur around the sites of brain hemorrhages, infarcts, or contusions due to a local plasma osmolality pressure gradient when compared to the high osmolality in the affected tissue.

Cerebral fungal abscesses are rare in immunocompetent hosts and are associated with high mortality, even with aggressive management. 1,2 Aspergillus flavus in immunocompetent patients is often associated with slowly progressive granulomatous sinusitis. It tends to cause central nervous system infection typically by angioinvasion. 3 However, angioinvasion could be absent in the beginning

Acute disseminated encephalomyelitis (ADEM), as the name would suggest, is featured by a monophasic acute inflammation and demyelination of white matter typically following a recent (1-2 weeks prior) viral infection or vaccination 4,6. MRI is also more sensitive to the complications of subdural empyemas, e.g. cerebritis, cerebral abscess, and venous thrombosis. Treatment and prognosis. Mortality associated with subdural empyemas now approaches 10%, compared with approximately 15-40% in the pre-CT era 1.
