Salmonellabrain abscess in a patient on chronic azathioprine therapy for myasthenia gravis: report of an unusual case and review of literature in the postantibiotic era

Focal intracranial infections caused by Salmonella species in adults are exceedingly uncommon. Structural brain injury with coexisting immunocompromised status appears to predispose adults to this rare manifestation of Salmonella infection. We report a case of Salmonella brain abscess in a patient with myasthenia gravis on chronic azathioprine therapy without any prior structural brain lesion. We reviewed world literature and discuss their analysis of Salmonella brain abscess in adult population in the postantibiotic era.
