INTRODUCTION
A 50-year-old man developed intermittent paresthesia of the outer portion of the right thumb. Paresthesia increased with thumb abduction and flexion. The remainder of the physical examination was normal.
METHODS
Routine motor and sensory examinations of the median and ulnar nerves were within normal ranges.
RESULTS
Ultrasonographic studies revealed that a tenosynovitis of the flexor pollicis longus of the right thumb was compressing the radial digital nerve of the thumb.
CONCLUSIONS
Ultrasonographic evaluation was used in conjunction with nerve conduction studies to diagnose digital neuropathy. Ultrasound is a beneficial, complementary tool to electrodiagnostic studies, especially for uncommon focal neuropathies.
简介
一名 50 岁男性出现右侧拇指外侧间歇性感觉异常。感觉异常随着拇指外展和弯曲而增加。其余体检正常。
方法
正中神经和尺神经的常规运动和感觉检查均在正常范围内。
结果
超声研究显示，右侧拇指屈拇长肌腱鞘炎压迫拇指桡侧指神经。
结论
超声评估结合神经传导研究用于诊断指神经病变。超声是电诊断研究的有益补充工具，特别是对于不常见的局灶性神经病。
