腕部急性尺神经病变是一种极其罕见的疾病，有时需要高度警惕才能诊断。由于远端部位神经的解剖走行复杂，手腕和手部尺神经病变的临床表现有所不同。我们报告了一例由盖恩管神经节引起的腕部急性尺神经病变，最初被误解为屈肌腱鞘炎。电生理学对尺神经选择性远端运动神经病进行了准确诊断。磁共振成像显示，有一个边界清晰的软组织肿块，与神经节一致，压迫盖恩管中的尺神经。卡压性神经病是理疗师治疗的常见病症之一。在对手腕或手部疼痛的患者进行鉴别诊断时，应牢记手腕处的尺神经病变。磁共振成像是急性局灶性神经病解剖学评估的有用方法。
Acute ulnar neuropathy at the wrist is an extremely uncommon condition, at times requiring a high index of suspicion for the diagnosis. Clinical presentations of ulnar nerve lesions at the wrist and hand show variations due to the complex anatomic course of the nerve in distal sites. We report a case of acute ulnar neuropathy at the wrist caused by a ganglion in Guyon’s canal, being initially misinterpreted as flexor tenosynovitis. The accurate diagnosis of selective distal motor neuropathy of ulnar nerve was made electrophysiologically. Magnetic resonance imaging revealed a well defined soft tissue mass consistent with a ganglion, compressing the ulnar nerve in Guyon’s canal. Entrapment neuropathies are one of the common conditions handled by physiatrists. Ulnar nerve lesions at the wrist should be kept in mind in the differential diagnosis of patients with wrist or hand pain. Magnetic resonance imaging is a useful method in the anatomical evaluation of acute focal neuropathies.
