Over the last 3 years we have observed 5 cases of median nerve schwannoma that clinically simulated carpal tunnel syndrome (CTS). We describe the atypical clinical-neurophysiological picture indicating to perform ultrasonography (US). We retrospectively re-evaluated 5 cases of schwannoma that clinically simulated CTS. Five consecutive patients were referred to the neurophysiopathology laboratory. All patients complained of symptoms and had a neurophysiological examination that might have indicated CTS. Nevertheless we performed US because of some incongruous aspects. In cases of atypical abnormalities at neurophysiological and clinical examination, or dissociation between neurophysiological and clinical findings, physicians should consider the presence of a median nerve tumour. Here, US evaluation is very useful as supporting diagnostic methodology to assess the anatomopathological condition of the nerve lesion and must not be limited to the wrist.
在过去3年里，我们观察到5例正中神经施万瘤，其临床表现酷似腕管综合征（CTS）。我们描述了提示需进行超声检查（US）的非典型临床-神经生理学表现。我们回顾性地重新评估了5例临床表现酷似CTS的施万瘤病例。连续5例患者被转诊至神经生理病理学实验室。所有患者均有症状，并进行了可能提示CTS的神经生理学检查。然而，由于一些不一致的方面，我们还是进行了超声检查。在神经生理学和临床检查出现非典型异常，或神经生理学与临床结果不一致的情况下，医生应考虑正中神经肿瘤的存在。在此，超声评估作为一种辅助诊断方法，对于评估神经病变的解剖病理学状况非常有用，且不应局限于腕部。
