Brachial neuritis is a rare disorder affecting the brachial plexus. It is characterized by the acute onset of shoulder and arm pain followed by weakness, sensory loss and atrophy. Diagnosis is essentially clinical with electrophysiological investigations and imaging useful in excluding other differentials and supporting the diagnosis. Magnetic resonance imaging (MRI) usually does not show any pathology in the brachial plexus or spinal cord. We present a case of a patient who had brachial neuritis preceded by varicella zoster infection. This was supported by MRI which showed abnormal signal consistent with inflammatory changes in the brachial plexus.
臂丛神经炎是一种罕见的疾病，影响臂丛。其特征是急性发作的肩部和手臂疼痛，随后出现无力、感觉丧失和萎缩。诊断主要依靠临床检查，电生理检查和影像学检查有助于排除其他鉴别诊断并支持诊断。磁共振成像（MRI）通常不会显示臂丛或脊髓有任何病理改变。我们报告一例臂丛神经炎患者，其前驱病为水痘-带状疱疹感染。MRI 支持这一诊断，显示臂丛有异常信号，符合炎症改变。
