Viral infections involving the central nervous system (CNS) may result from a wide variety of agents and have clinically overlapping manifestations. The diagnosis is often made based on a combination of the clinical exam, local epidemiology, imaging, and biochemical findings. Despite the advances in medicine and imaging, the diagnosis often remains elusive. Imaging, however, still plays a vital role in suggesting the diagnosis in typical cases, excluding potential mimics, and in evaluating changes with therapy. Herein, the authors present a review of various common and rare viral encephalitides with emphasis on the imaging literature.
涉及中枢神经系统（CNS）的病毒感染可能由多种病原体引起，且具有临床上相互重叠的表现。诊断通常基于临床检查、当地流行病学、影像学和生化检查结果的综合判断。尽管医学和影像学取得了进展，但诊断往往仍难以明确。然而，影像学在典型病例的诊断提示、排除潜在的相似病症以及评估治疗效果方面仍起着至关重要的作用。在此，作者对各种常见和罕见的病毒性脑炎进行综述，重点关注影像学文献。
