This article outlines a practical imaging approach to CNS infection and reviews 5 basic imaging patterns commonly seen: (1) extra-axial lesion, (2) ring-enhancing lesion, (3) temporal lobe lesion, (4) basal ganglia lesion, and (5) white matter abnormality. Opportunistic infections in the setting of HIV are also discussed within the context of these 5 basic imaging patterns. Characteristic imaging features in conjunction with clinical history are also highlighted in order to narrow the differential diagnosis or suggest a specific diagnosis in some cases.
本文概述了中枢神经系统感染的一种实用影像学方法，并回顾了 5 种常见的基本影像学表现：（1）脑外病变；（2）环形增强病变；（3）颞叶病变；（4）基底节病变；（5）脑白质异常。本文还结合这 5 种基本影像学表现讨论了 HIV 背景下的机会性感染。为了在某些情况下缩小鉴别诊断或提示特定诊断，本文还强调了特征性影像学表现结合临床病史的重要性。
