Reported here is a 46-year-old man who was seen for pain, numbness, and weakness in his left upper limb and hand. Electromyographic studies demonstrated denervation of ulnar-innervated muscle groups except for the flexor carpi ulnaris. A localized nerve conduction block could not be depicted because of severe axonal loss. Ultrasonographic evaluation showed enlargement of the ulnar nerve at 2 sites: at the level of the epicondylar groove and the inside of the flexor carpi ulnaris muscle. Herein, we would like to emphasize the complementary role of an ultrasound in peripheral nerve pathologies, not only does it confirm the entrapment but it also displays the underlying cause(s).
现报告一例 46 岁男性，因左上肢和手部疼痛、麻木和无力就诊。肌电图研究显示尺神经支配的肌肉群除了尺侧腕屈肌以外均有失神经支配。由于轴突大量丢失，无法描绘局部神经传导阻滞。超声检查显示尺神经在 2 个部位增大：髁突沟水平和尺侧腕屈肌内。在此，我们想强调超声在外周神经病变中的补充作用，它不仅可以确认神经受压，还可以显示潜在的病因。
