Central nervous system involvement in melioidosis is rare. We describe a 48 year old woman who developed septicaemia and a brain abscess due to Pseudomonas pseudomallei. Since there is a continuing practical problem in bacteriological confirmation of the aetiological agent, diagnosis of melioidosis has to be made on clinical suspicion.

The diagnosis of intracranial focal lesions based on imaging studies is a challenge. In brain abscess, proton magnetic resonance spectroscopy (1H-MRS) is useful to define etiology, differentiating anaerobic from aerobic pathogens and inclusive sterile abscess based on the behavior of certain metabolites. We report a patient with Rendu-Osler-Weber syndrome, pulmonary arteriovenous fistulas, and ...

Brain abscess is an extremely rare manifestation of tuberculous involvement of the CNS; meningitis and tuberculoma are much more common [1-6]. The CT appearance of tuberculous abscess cannot be distinguished from many other entities that can present as a ring-enhancing lesion, such as pyogenic abscess, primary or metastatic neoplasm, or resolving hematoma. However, given the appropriate history...

Although intracranial mass lesions that occur as a result of infection have commonly been reported in patients infected with human immunodeficiency virus, polymicrobial pyogenic brain abscess has not been described in this setting. We report the first case of a patient with a polymicrobial brain abscess involving Streptococcus bovis, Fusobacterium necrophorum, Peptostreptococcus, and group G St...

A bacteriologically confirmed case of tuberculous abscess of the brain is reported. Tuberculous brain abscess unlike tuberculoma does not exhibit the typical granulomatous changes and the diagnosis is confirmed by demonstration of tubercle bacilli either by staining or culture. An antituberculous regime should be started immediately the diagnosis has been established.
