A young patient with symptoms of median nerve compression in carpal tunnel without known risk factors is presented. Ultrasonography and magnetic resonance imaging confirmed an anatomical variation of the median nerve in carpal tunnel, described in the literature as bifid median nerve. The knowledge of the existence ofbifid median nerve is important in planning surgical decompression of median nerve to avoid nerve injury or potential relapse if decompression of both branches has not been done. Carpal tunnel ultrasonography is a noninvasive, reliable and available diagnostic tool to diagnose bifid median nerve.
本文介绍了一名年轻患者，其患有腕管综合征正中神经受压症状，但无已知风险因素。超声检查和磁共振成像证实了腕管内正中神经的解剖变异，文献中描述为正中神经分支。了解正中神经分支的存在对于计划正中神经手术减压非常重要，以避免神经损伤或如果未对两个分支进行减压可能出现的复发。腕管超声检查是诊断正中神经分支的一种无创、可靠且可用的诊断工具。
