Salmonella brain abscess in an infant.

Brain abscess is a potentially life-threatening condition requiring rapid diagnosis and prompt medical and surgical intervention. Various etiological agents associated with different epidemiological backgrounds are implicated, including Gram-positive and Gram- negative bacterial agents as well as anaerobes. Salmonella is rarely reported to be the cause of this medical condition despite being known to cause invasive infections at extremes of age and the fact that this organism is a common cause of other clinical infectious diseases encountered in immunocompromised and immunocompetent individuals. A case of Salmonella brain abscess involving the right posterior parietal region of the brain is described in a 6-month-old infant. The clinical, microbiological, and radiological features, as well as the clinical management and outcome, are presented. This case highlights the slow-progression nature of brain abscess caused by Salmonella species and the challenge in achieving optimal resolution despite initial surgical intervention.
