高频超声在外周神经鞘瘤诊断中的应用价值

High-frequency ultrasound in peripheral neurilemmoma diagnosis application value

目的探讨高频超声在外周神经鞘瘤诊断中的应用价值。方法回顾性分析经手术病理证实的外周神经鞘瘤37例,对其声像图表现进行总结,并与其易误诊病变进行鉴别诊断。结果外周神经鞘瘤在声像图表现上可分为三型,无论是何种分型均可在肿瘤长轴的一端或两端边缘找到与之相连的神经干细尾状低回声,称"鼠尾征"。结论高频超声声像图特征结合临床能够比较准确地对外周神经鞘瘤作出诊断,在外周神经鞘瘤的诊断中有重要的实用价值。

Objective Discussion of high-frequency ultrasound in peripheral neurilemmoma diagnosis application value. Methods Retrospective analysis confirmed by surgery and pathology of peripheral neurilemmoma in 37 cases, Their performance ultrasound to sum up, Misdiagnosed disease and its differential diagnosis. Results Peripheral neurilemmoma in the imaging performance can be divided into three types, No matter what type of tumor may be in the long axis of one end or both ends to find the edge associated with neural stem-like low-end small echo, “the rat tail sign”. Conclusion High-frequency ultrasound imaging to compare the clinical characteristics of the combined precisely peripheral neurilemmoma diagnosed, peripheral neurilemmoma diagnosis has important practical value.
