INTRODUCTION
Diagnostic nerve ultrasound is becoming more commonly used by both radiologists and clinicians. The features of different neuromuscular conditions must be described to broaden our understanding and ability to interpret findings.
METHODS
Our study examines the sonographic features of 7 subjects with hereditary neuropathy with liability to pressure palsies (HNPP) in comparison to 32 controls by measuring the nerve cross-sectional area (CSA) of the median, ulnar and tibial nerves.
RESULTS
Significant differences (P < 0.05) in nerve size were found. The HNPP group had a larger CSA for the median nerve at the wrist and ulnar nerve at the elbow (entrapment sites), but not the forearms. The tibial nerve at the ankle was also larger in the HNPP group, suggesting possible concomitant tibial neuropathy at the ankle.
CONCLUSION
These results will help shape imaging protocols to better detect conditions with non-uniform nerve enlargements.
简介
诊断神经超声越来越受到放射科医生和临床医生的广泛应用。必须描述不同神经肌肉疾病的特征，以拓宽我们的理解和解释发现的能力。
方法
我们的研究通过测量正中神经、尺神经和胫神经的神经横截面积（CSA），比较了 7 名遗传性压力易发性神经病（HNPP）患者和 32 名对照者的超声特征。
结果
发现神经大小存在显著差异（P < 0.05）。HNPP 组在腕部的正中神经和肘部的尺神经（受压部位）CSA 较大，但在前臂则不然。HNPP 组在踝关节的胫神经也较大，提示可能同时存在踝关节的胫神经病变。
结论
这些结果将有助于制定成像方案，以更好地检测非均匀性神经增大的情况。
