Abstract

We present a case of Listeria monocytogenes cerebral abscess with axonal spread via the subcortical U-fibres and extreme capsule on magnetic resonance imaging, with follow-up studies demonstrating serial reduction in oedema and enhancement pattern of the white-matter fibre tracts following antimicrobial treatment. We discuss the microbiological mechanism of bacterial mobility to account for these unique imaging features. Recognition of this distinct pattern of spread of L. monocytogenes cerebral abscess may aid in diagnosis and enable early microbiological culture and treatment.

摘要

我们报告一例单核细胞增生李斯特菌脑脓肿病例,磁共振成像显示其通过皮质下U形纤维和外囊发生轴突扩散,随访研究表明抗菌治疗后水肿持续减轻,白质纤维束强化模式改善。我们讨论了细菌移动的微生物学机制,以解释这些独特的影像学特征。认识到单核细胞增生李斯特菌脑脓肿这种独特的扩散模式可能有助于诊断,并能实现早期微生物培养及治疗。
