The West Nile virus (WNV) is an arbovirus than can infect human beings and cause severe neuroinvasive disease. Taking the outbreak that occurred in Spain in 2020 as a reference, this article reviews the clinical and imaging findings for neuroinvasive disease due to WNV. We collected demographic, clinical, laboratory, and imaging (CT and MRI) variables for 30 patients with WNV infection diagnosed at our center. The main clinical findings were fever, headache, and altered levels of consciousness. Neuroimaging studies, especially MRI, are very useful in the diagnosis and follow-up of these patients. The most common imaging findings were foci of increased signal intensity in the thalamus and brainstem in T2-weighted sequences; we illustrate these findings in cases from our hospital.
西尼罗河病毒（WNV）是一种虫媒病毒，可感染人类并导致严重的神经侵袭性疾病。本文以 2020 年在西班牙发生的疫情为例，回顾了西尼罗河病毒引起的神经侵袭性疾病的临床和影像学表现。我们收集了在本中心诊断为西尼罗河病毒感染的 30 名患者的人口统计学、临床、实验室和影像学（CT 和 MRI）资料。主要的临床发现是发热、头痛和意识水平改变。神经影像学研究，特别是 MRI，在这些患者的诊断和随访中非常有用。最常见的影像学表现为 T2 加权序列中丘脑和脑干的信号强度增高病灶；我们展示了来自我们医院的病例中的这些表现。
