Multifocal nerve enlargements and ultrastructural changes either corresponding or not to sites of existing conduction blocks have been described in demyelinating polyneuropathies using multiple imaging techniques.
Using the emerging technique of peripheral nerve ultrasonography we investigated the peripheral nerves of a patient with multifocal motor neuropathy (MMN) without conduction block.
In this case of MMN without conduction blocks we found multifocal nerve enlargements in the ultrasonography and electrodiagnostic signs of acute and chronic denervation associated with positive anti-GM1 IgM antibodies.
This case shows that nerve ultrasound can be a complementary tool for diagnosing multifocal motor neuropathy without typical electrodiagnostic features.
使用多种成像技术已在脱髓鞘性多发性神经病中描述了多灶性神经增粗以及与现有传导阻滞部位相符或不相符的超微结构变化。
我们使用新兴的周围神经超声技术，对一名无传导阻滞的多灶性运动神经病（MMN）患者的周围神经进行了研究。
在这例无传导阻滞的MMN病例中，我们在超声检查中发现了多灶性神经增粗，以及与抗GM1 IgM抗体阳性相关的急慢性失神经支配的电诊断体征。
该病例表明，神经超声可作为诊断无典型电诊断特征的多灶性运动神经病的辅助工具。
