摘　　要：目的探讨高频超声直接及间接征象对外周神经鞘瘤的诊断价值。方法回顾性分析该院经病理证实的26例神经鞘瘤的声像图特征。结果声像图表现为单发结节,17例呈实性,9例呈混合性,包膜完整,内部可见血流信号。直接征象:17例瘤体两端可见神经干结构,3例瘤体一端可见与神经干相连。间接征象:2例瘤体周围可见同名血管伴行,且瘤体在神经走行区域内。超声诊断神经鞘瘤20例(76.9%),2例误诊为神经纤维瘤(7.7%),4例未明确诊断(13.4%)。结论术前明确诊断是术中防止神经损伤的关键。高频超声在诊断外周神经鞘瘤方面有较高的应用价值,可成为外周神经源性肿瘤重要的影像学检查手段。[Objective] To assess the value of high-resolution uhrasonography direct and indirect signs in diagnosis of peripheral neurilemmoma. [Methods ] Retrospectively reviewed the uhrasoundic features of 26 pa- tients pathologically proven peripheral neurilemmoma. [Results] All patients were solitary, 17 patients were solid and 9 patients were complex echogenicity. The capsure was clear. And all of them showed blood flow. Direct signs： 17 cases can be seen neural stem at both ends of the tumor and 3 cases can be seen at one end. Indirect signs： 2 cases can be seen vascular accompany and the tumor traveled in the nerve distribution area. 20 cases were diagnosed as peripheral neurilemmoma （76.9%）, 2 cases were misdiagnosed as neurofibro- ma （7.7%）, 4 cases were not definitely diagnosed （13.4%）. [Conclusion] Preoperative diagnosis is the key to prevent intraoperative damage to the nervous. High-frequency uhrasonography is useful in evaluating the pe- ripheral neurilemmoma and may become an important imaging method.
