De Quervain's stenosing tenosynovitis of the first dorsal extensor component is traditionally diagnosed clinically but may be encountered when performing MRI of the wrist. A retrospective review of wrist MR images was performed in cases where the diagnosis of de Quervain's synovitis was suggested (n = 5). Imaging findings were correlated with clinical findings in four cases and with wrist arthroscopy in one case. Increased thickness of the extensor pollicus brevis and abductor pollicis longus tendons was the most reliable finding on MRI, being present in all cases. Peritendinous edema was also a reliable finding. Surrounding subcutaneous edema and increased intratendinous signal were less reliable findings in confirmed cases of de Quervain's disease. De Quervain's tenosynovitis may be encountered when performing MRI of the wrist. Increased tendon thickness and peritendinous edema are the most reliable imaging findings.
第一背侧伸肌成分的桡骨茎突狭窄性腱鞘炎传统上通过临床诊断，但在进行腕关节磁共振成像（MRI）时也可能发现。对提示桡骨茎突腱鞘炎诊断的病例（n = 5）进行了腕关节MR图像的回顾性研究。4例的影像学表现与临床发现相关，1例与腕关节镜检查结果相关。拇短伸肌腱和拇长展肌腱增厚是MRI上最可靠的表现，所有病例均有此表现。肌腱周围水肿也是可靠的表现。在确诊的桡骨茎突疾病病例中，周围皮下水肿和肌腱内信号增加的可靠性较低。在进行腕关节MRI时可能会发现桡骨茎突腱鞘炎。肌腱增厚和肌腱周围水肿是最可靠的影像学表现。
