Causes, incidence, and risk factors Return to top Brain abscesses commonly occur when bacteria or fungi infect part of the brain. Inflammation develops in response. Infected brain cells, white blood cells, and live and dead microorganisms collect in a limited area of the brain. This area becomes enclosed by a membrane that forms around it and creates a mass. While this immune response can protect the brain by isolating the infection, it can also do more harm than good. The brain swells in response to the inflammation, and the mass may put pressure on delicate brain tissue. Infected material can block the blood vessels of the brain, further damaging tissues by causing cell death and swelling of additional cells. Multiple abcesses are uncommon except in immunocompromised patients.

   Extractions: Peer Review Status: Internally Peer Reviewed At least 75% of cerebral abscesses are associated with infections elsewhere in the body. In the preantibiotic era, most brain abscesses were secondary to direct extension of infections of the mastoid region, middle ear, or the paranasal sinuses. Since the advent of antibiotics, however, most infections associated with cerebral abscesses are localized to the lungs and endocardium. There is a predominance of cerebral abscesses in males by a ratio of 2:1, and 50% of cases have multiple sites of CNS involvement. Clinically, the course of the primary infection varies from months to years, but once CNS symptoms arise the clinical course progresses rapidly downhill despite antibiotic treatment. The mortality rate varies from 33 to 50%. The organisms most commonly responsible for cerebral abscesses are listed here . Other organisms which may produce a cerebral abscess in rare situations are the coliforms and actinomyces. Occasionally, cultures will show a mixed population of organisms, and about 25% of cultured abscesses will be sterile. Besides bacteria, certain fungi and parasites may also produce abscees under special conditions which will be discussed below. The most common location of an abscess in the CNS depends on the source of the infection. With blood-borne infections, an abscess may form anywhere in the CNS with equal likelihood, whereas those seeded from mastoid infections usually result in an abscess in the posterior fossa. Abscesses which arise secondarily to infections of the paranasal sinuses are usually found in the frontal lobes.

    Extractions: Causes, incidence, and risk factors: A brain abscess is usually caused when bacteria such as staphylococci and streptococci infect part of the brain. In response to the infection, there is inflammation and death of some of the tissues in the brain. Fluid, destroyed tissue cells, white blood cells, and live and dead microorganisms collect and form a mass. This mass usually becomes enclosed by a membrane that forms around it.

Multiple abcesses are uncommon except in immunocompromised patients. Infectious agents gain access to the brain in several ways. The most common way is through infected blood. Ear and sinus infections may also spread directly to the brain because of their close proximity.

    Extractions: Medication, not surgery, is advised for multiple abscesses, a small abscess (less than 2 cm), an abscess deep within the brain, an abscess accompanied by meningitis , the presence of shunts in the brain (for hydrocephalus ), or an underlying disease that makes surgery dangerous (debilitating disease). Antimicrobials are given, initially through a vein, then by mouth. Antibiotics which work against a number of different bacteria (broad spectrum antibiotics) are the most common antimicrobial prescribed. It is not uncommon for multiple antibiotic medications to be used in order to ensure effective treatment of the infection. Antifungal medications may also be prescribed if fungal infection is likely. The presence of a compressive lesion (which is injuring brain tissue by pressing on it) or a large abscess with a high degree of swelling around it can raise intracranial pressure to the point where immediate treatment is needed.

Accessibility Out There Links Notice Board Computed tomography scan of cerebral abscess Case history An 82 year old woman was admitted as an emergency, having had a generalised tonic-clonic seizure witnessed by her husband. She had no prior history of epilepsy and no history of trauma. According to her husband she was reasonably well and had not seen a doctor for more than 20 years. She had no history of any drug allergy and was not taking any regular medication. She was a lifelong non-smoker and infrequent social drinker. Computed tomography scan of cerebral abscess A consultant dermatologist confirmed the lesion behind her ear as a basal cell carcinoma and arranged for her to have radiotherapy. There was no evidence of sinusitis, but it was felt that the patient had a middle ear infection. She received dexamethasone and sodium valproate with blind antibiotic therapy for six weeks in total. However, blood cultures, swabs, and culture of aspirate taken during surgical aspiration were all negative. She was discharged home at seven weeks Questions What does the computed tomography scan show?
