A 63-year-old right-handed office worker presented with acute right wrist pain after lifting a heavy file at work. Results of a clinical examination suggested flexor carpi radialis tendinopathy. Diagnostic ultrasound (US) not only detected a complete flexor carpi radialis tear but also revealed the presence of a concomitant flexor carpi radialis brevis (FCRB) tendon with associated tenosynovitis. The ability of US to correctly identify the FCRB has not been previously reported. Furthermore, the US appearance of FCRB tendinopathy and tenosynovitis has not been described. High-resolution US can identify the FCRB muscle-tendon in the wrist region. Sonologists and sonographers should be aware of the US appearance of the FCRB as well as the potential for the FCRB to contribute to radial wrist pain syndromes.
一名63岁的右利手办公室职员在工作中搬起一份沉重文件后出现右腕急性疼痛。临床检查结果提示桡侧腕屈肌腱病。诊断性超声（US）不仅检测到桡侧腕屈肌完全撕裂，还发现存在一条伴发的桡侧腕短屈肌（FCRB）肌腱及相关腱鞘炎。此前尚未有关于超声正确识别FCRB的报道。此外，FCRB肌腱病和腱鞘炎的超声表现也未被描述。高分辨率超声能够识别腕部区域的FCRB肌腱。超声科医生和超声检查人员应了解FCRB的超声表现以及FCRB导致桡侧腕部疼痛综合征的可能性。
