Cerebral melioidosis in Singapore: a review of five cases

A variety of neurological manifestations of infection with Burkholderia pseudomallei have been described including cerebral abscesses, which are a well-recognized form of neurological melioidosis. The optimal antibiotic therapy for this condition has not been defined; however, combinations of intravenous antibiotics are frequently used in the early stages. Five cases of melioidosis involving brain abscesses are described which presented in Singapore over the past 3 years (1997-2000), 4 of which cases had evidence of disseminated infection. Despite profound neurological deficits and low Glasgow Coma Scale scores at presentation in 3 of these cases, all survived after surgical drainage and prolonged courses of intravenous ceftazidime or imipenem, and only 2 of whom had residual neurological impairment. One incidental finding on computed tomography (CT) or magnetic resonance imaging (MRI) scans not described before as an association with cerebral melioidosis was sinusitis in 4 out of the 5 cases.
