Brain abscess caused by Salmonella Enteritidis following craniotomy for meningioma: A case report and literature review.

Salmonella intracranial infection is infrequently encountered in clinical practice. However, with prompt intervention and appropriate antimicrobial therapy, the outcome is usually favourable. A 56-year-old gentleman who worked as an organic fertilizer production supervisor underwent tumour resection for meningioma located at the left frontal temporoparietal region. The surgical procedure went smoothly, and he has prescribed dexamethasone thereafter. He was discharged well. However, a few days after that he developed a fever associated with pus discharged from the surgical wound. A computed tomography (CT) scan of the brain was performed and it revealed an abscess located at the left frontal temporoparietal subdural and subgaleal regions with adjacent cerebritis. Another craniotomy was done to drain the abscess. The bacterial culture of the pus specimen grew Salmonella Enteritidis. The bacterium was susceptible to ciprofloxacin, ceftriaxone, and amoxicillin-clavulanic acid. Clinical improvement was evident after surgical intervention with an additional 6 weeks of ceftriaxone therapy.
