Alternative Names Abscess - brain; Cerebral abscess; CNS abscess Causes 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.

The clerking doctor noted that she had been discharged from the ENT ward 19 days earlier after treatment for chronic otitis media. He also recorded a history of many episodes of bile-stained vomit, anorexia, weight loss, constipation and frontal headaches. On examination, the only finding of note was tenderness on deep palpation of the epigastrium and left upper quadrant of the abdomen. Dr T, an SHO, saw Ms C later the same day. He noted pus in the right ear with a pink tympanic membrane. There was no neck stiffness. He diagnosed an upper respiratory tract infection with right otitis media, ordered FBC, ESR, right ear swab, throat swab and MSU, and started Ms C on a broad-spectrum penicillin. At review the following day, Dr T discovered that a right ear swab taken at the ENT outpatient’s had grown pseudomonas resistant to penicillin, so he put Ms C on gentamicin and asked that the gentamicin levels be monitored.

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.

Findings: CT scan was performed before and after the administration of IV contrast and reveals a left cerebral mass abutting the falx. There is in addition surrounding edema extending superiorly with slight midline shift to the right. Subsequent to the administration of contrast, a rim of enhancement is evident. Differential Diagnosis: Brain abscess, neoplasm, granuloma, cerebral infarct, resolving hematoma. Diagnosis: Cerebral abscess Discussion: Between (30% and 60%) of pyogenic abscesses are mixed infections, with aerobic isolates outnumbering anaerobic isolates approximately 2 to 1. Organisms include streptococci, staph aureus, and now more frequently gram negative bacilli. It is also important to note that the immune status of the patient can influence the organism causing the abscess. In neutropenic patients, brain abscesses may be caused by candida or aspergillus. In patients with abnormal cell mediated immunity, the causes may include toxoplasma gondii, mycobacterium, nocardia, cryptococcus, or listeria. There are four stages in the evolution of a brain abscess.

cerebral abscess Brain abscesses may occur within the cerebral hemispheres or within the cerebellum. Solitary abscesses are most often located in the temporal lobe or cerebellum; multiple abscesses occur most often in the cerebrum at the junction of the white and grey matter. Rarely, brain abscess arise rapidly; more commonly, their development is gradual with three phases recognisable: invasion - headache, nausea, slight CSF changes latent - transient attacks of headache, malaise, etc. manifest - localising signs, CSF pressure effects Diagnosis is from the history, and is confirmed by CT scan.

Multiple abcesses are uncommon except in immunocompromised patients. The bacteria or fungi can reach the brain through the blood, by traveling from a neighboring infected area, or by direct contamination from an injury or surgery. Most commonly, the infectious organism reaches the brain via the bloodstream. The source of the infectious organism is often not found. When identified, the most common source is a lung infection.

Source: Neurological Research , Volume 25, Number 1, January 2003, pp. 27-30(4) Publisher: Maney Publishing View Table of Contents full text options Abstract: Nocardia asteroides cerebral abscesses are rare but challenging intracranial lesions. Early diagnosis, institution of appropriate antimicrobial therapy, lack of underlying systemic disease and limited intracranial disease are recognized factors leading to good outcome. However, the optimal treatment approach has not been established and nocardial brain abscesses have been managed either conservatively, with stereotactic aspirations or with open craniotomy and enucleation. We present three cases of Nocardia asteroides cerebral abscesses cured only after neurosurgical enucleation, and discuss the current management alternatives and conclude that a more aggressive approach than that currently preferred for this entity may be more effective.

Cerebral Phaeohyphomycosis caused by Ramichloridium mackenziei in the Eastern Province of Saudi Arabia Tahir Q. Kashgari, DMRD; Hani Al-Miniawi, MD; Maher K. Moawad Hanna, MSc PhD A brain abscess is a localized collection of pus within the brain parenchyma or meninges. A wide range of micro-organisms have been identified as causative agents, depending on the source of infection and predisposing conditions. A few published data are available on the microbiology of cerebral abscesses from developing countries. Human brain abscesses due to fungi are mostly seen in immunocompromised patients with opportunistic infections. They have also been seen in patients on cytotoxic drugs, long-term corticosteroid treatment, and those with diabetes mellitus. These abscesses have been caused by various species such as aspergillus candida Zygomycetes, Cryptococcus neoformance, Blastomyces dermatitidis, Coccidioides immitis , and Pseudallescheria boydii. However, basidiomycete Schizophyllum commune has also been reported as an emerging pathogen which was found involving the lungs of a 58-year-old patient, with subsequent dissemination to the brain. Phaeohyphomycosis is a term initially proposed by Ajello and Georg in 1974 for fungal infection characterized by dematiaceous (because of the dark pigment, dihydroxy-naphthalene melanin, present in the cell wall) septated mycelial elements in tissues. The more general term, "cerebral phaeohyphomycosis," is applicable to all brain infections caused by dematiaceous fungi. These organisms are being increasingly recognized as opportunistic pathogens that can cause serious disease in immunocompromised patients.

It is fatal if untreated and requires immediate hospitalization. Detailed Information 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.
