Brachial plexopathy is an uncommon neurologic complication of varicella-zoster virus (VZV) infection. VZV is not an acquired immunodeficiency syndrome-defining illness, but human immunodeficiency virus (HIV) infection is a risk factor for atypical and severe complications of VZV reactivation. Here, we present a 70-year-old male, who presented with left upper-limb weakness, preceded by painful dermatomal vesicular eruption, and was diagnosed to have zoster brachial plexopathy. This severe and atypical manifestation of VZV prompted HIV infection testing, leading to a new diagnosis of HIV infection.

带状臂丛神经病是人类免疫缺陷病毒感染的表现形式

臂丛神经病变是水痘带状疱疹病毒（VZV）感染的罕见神经系统并发症。VZV不是定义为获得性免疫缺陷综合症的疾病，但是人类免疫缺陷病毒（HIV）感染是VZV重新激活的非典型和严重并发症的危险因素。在这里，我们介绍了一个70岁的男性，其表现为左上肢无力，先是疼痛性的皮肤皮肤水疱疹，并被诊断出患有带状臂丛神经病变。VZV的这种严重和非典型表现促使HIV感染检测，从而导致对HIV感染的新诊断。
