   A cerebral abscess is caused by infection that spreads to the brain.  
   http://www.body1.com/care/index.cfm/2/162
   
   Extractions: Discuss this Condition A cerebral abscess is a collection of pus that occupies space in the brain. It is fatal if untreated and requires immediate hospitalization. A cerebral abscess is caused by infection that spreads to the brain. The infection causes inflammation and kills brain tissue. The dead tissue then collects with other cells and microorganisms in the brain to form a mass encapsulated by a membrane. The mass swells, and brain pressure increases. The increased pressure, in turn, causes more damage to brain tissue. There are many possible sources of the infection causing the abscess. Chronic ear and sinus infections together cause more than one-third of all cerebral abscesses. Injury can also lead to abscess: compound fracture can leave a piece of bone or foreign tissue in the brain that can become an abscess even 20 or 30 years after the initial injury. Mastoiditis (skull infection), skin infections, congenital heart disease, lung abscess, empyema, endocarditis and bronchiectasis can also cause abscesses to form. In some cases of cerebral abscesses, the underlying cause is not determinable.

   Extractions: Click on Images for Enlarged View Clinical History: The patient has a history of a left parietal brain metastasis secondary to lung cancer. This lesion was previously treated with chemotherapy and gamma knife radiation. The patient now presents with a three week history of progressive right sided paresis. Findings: A brain MRI was performed. The patient's region of previous metastasis demonstrates an area of encephalomalacia on FLAIR images with surrounding increased signal, likely representing gliosis. In addition, a left frontal mass is seen with surrounding increased signal, likely representing vasogenic edema. T1 weighted post contrast axial images demonstrate ring enhancement of the left frontal lesion but no enhancement of the left parietal region. Finally, diffusion weighted images demonstrate abnormally increased signal centrally within the left frontal region but decreased signal centrally within the left parietal region. Diagnosis: Cerebral abscess.

   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.

Causes, incidence, and risk factors Return to top Tooth abscess is a complication of dental caries . It may also result from trauma to the tooth (such as when a tooth is broken or chipped). Openings in the tooth enamel allow bacteria to infect the center of the tooth (the pulp). Infection may spread out from the root of the tooth and to the bones supporting the tooth. Infection results in a collection of pus (dead tissue, live and dead bacteria, white blood cells) and swelling of the tissues within the tooth. This causes a painful toothache . If the root of the tooth dies, the toothache may stop, but the infection remains active and continues to spread and destroy tissue.

The inner portion of the wall is formed by a layer of neutrophils and fibrin, the middle portion consists primarily of fibrous tissue (blue staining tissue with trichrome stain), and the outer portion is made up of reactive glia. It is noteworthy that abscesses are virtually the only pathologic entity in the CNS in which the repair process is dominated by fibrosis rather than gliosis.

    http://www.mribhatia.com/braintf18/braintf18text.html
    
    Extractions: BrainTF18 -Cerebral Abscess (Pyogenic) Clinical Profile: Patient presented with headaches, fever and neck rigidity. CSF findings were suggestive of pyogenic meningitis. Findings: There is a well defined hyperintense lesion with a hypointense rim on the T2W images in the left para-atrial region. It is hypointense on the T1W images and reveals rim enhancement. Perilesional edema is noted with resultant mass effect. The CSF in the posterior body and atrium of the left lateral ventricle appears more hyperintense than normal and the ventricular wall in that region shows a hyperintense signal on the FLAIR images. This wall is also seen to enhance. Discussion: Pyogenic bacterial infection of the CNS may present as focal cerebritis, abscess, meningitis and/or subdural/epidural empyema. It may result from direct spread of infection, either ENT infection or meningitis or from hematogenous spread from an extracranial source of infection. Pathogenesis: Cerebritis is a localized yet poorly demarcated area of parenchymal softening with scattered necrosis, edema, vascular congestion, petechial hemorrhage and perivascular inflammatory infiltrates. It progresses to an abscess when the central zone of necrosis within, becomes liquefied, better defined and encircled by a collagen capsule (is surrounded by a zone of gliosis). The collagen capsule is less well developed on its ventricular side than on its cortical side, probably related to slight differences in perfusion. The time required to form a mature abscess varies from 2 weeks to several months. In adults, abscesses arising from hematogenous spread are most often caused by anaerobic bacteria or a mixture of anaerobes and aerobes. In children, staphylococci, streptococci, and pneumococci are the most common pathogens. In patients with a history of trauma or prior neurosurgical procedure, abscesses are usually due to Staphylococcus aureus.
