Giant intracranial Brucella abscess after head trauma: a Case Report of neurobrucellosis in an urban elderly male without exposure history

Résumé fourni par la source

Giant intracranial Brucella abscess is a severe and rare central nervous system infection whose pathogenesis remains incompletely understood. We detail the case of a 75-years-old urban male without Brucella exposure history who presented with fever and headache. Initial attribution of cephalgia to head trauma delayed diagnosis and treatment. Magnetic resonance imaging, metagenomic next-generation sequencing, and cerebrospinal fluid culture confirmed rapid development of a giant Brucella abscess (31 mm × 58 mm) within 2 weeks after head trauma. Head trauma may be potentially associated with the formation of Brucella brain abscess. Consequently, brucellosis patients with recent head trauma may warrant vigilant monitoring for this rare complication. It is imperative to avoid the premature attribution of headache to head trauma in such patients, as such an oversight risks delaying the diagnosis and management of a Brucella brain abscess.
