Introduction: Nerve ultrasound has been used increasingly in clinical practice as a complementary test for diagnostic assessment of neuropathies, but nerve biopsy remains invaluable in certain cases. The aim of this study was to compare ultra–high‐frequency ultrasound (UHF‐US) to histologic findings in progressive polyneuropathies. Methods: Ten patients with severe, progressive neuropathies underwent ultrasound evaluation of the sural nerve before nerve biopsy. Ultrasound data were compared with histologic results in a retrospective manner. Results: Sural nerves were easily identified on UHF‐US. Nerve hyperechogenicity correlated with inflammatory infiltrates on biopsy. Nerve fascicles could be identified and measured on ultrasound in the majority of patients. Discussion: Hyperechogenicity on UHF‐US may be a marker of nerve inflammation in neuropathies. Furthermore, the UHF‐US probe allows for evaluation of sensory nerves in spite of their small size, providing valuable information on their size and on their internal structure.

腓肠神经的超高频超声成像:进行性神经病变的神经活检的比较研究。

简介:神经超声在临床实践中已越来越多地用作对神经病进行诊断评估的补充测试,但在某些情况下神经活检仍具有不可估量的价值。这项研究的目的是将超高频超声(UHF-US)与进行性多发性神经病的组织学发现进行比较。方法:对10例重度,进行性神经病变的患者进行神经活检前,对腓肠神经进行超声检查。回顾性比较超声数据与组织学结果。结果:在UHF-US上很容易识别出神经。神经高回声性与活检中的炎症浸润相关。在大多数患者中,可以识别出神经束并进行超声测量。讨论: UHF-US的超强回生性可能是神经病变中神经炎症的标志。此外,UHF-US探头尽管尺寸很小,但仍可以评估感觉神经,从而提供有关其大小和内部结构的有价值的信息。
