High-resolution ultrasonography was performed on 14 patients with soft tissue swelling of the wrist and hand. The examination was done using a real-time 10-MHz sector probe placed directly on the lesion. The sonographic image could always demonstrate the liquid nature of cystic lesions. In recent ganglia, the fluid content was anechoic, and the cystic walls were rather thin; in some older lesions, irregular internal echoes and thicker walls were found. Rather often, multiple ganglia were observed, grouped in clusters. The presence of a liquid-filled duct directed to the articular space was demonstrated in 8/11 cases (73%). This finding is considered a diagnostic characteristic of ganglia, and it is very useful for correct surgical planning. In extensor cystic tenosynovitis, the echographic picture was quite different: the anechoic cavity was longitudinal in shape, following the tendon sheath, and the communicating duct was absent. Finally, the sonographic pattern of one case of de Quervain's disease was analyzed and discussed.
对14例手腕和手部软组织肿胀患者进行了高分辨率超声检查。检查使用直接放置在病变部位的实时10兆赫扇形探头进行。超声图像总能显示出囊性病变的液体性质。在近期的腱鞘囊肿中，液体成分为无回声，囊壁相当薄；在一些陈旧性病变中，发现内部回声不规则且壁较厚。相当常见的是，观察到多个腱鞘囊肿，聚集成簇。在11例中的8例（73%）中显示存在通向关节间隙的充满液体的管道。这一发现被认为是腱鞘囊肿的诊断特征，对正确的手术规划非常有用。在伸肌囊性腱鞘炎中，超声图像有很大不同：无回声腔呈纵向，沿腱鞘走行，且无连通管道。最后，对1例桡骨茎突狭窄性腱鞘炎的超声图像模式进行了分析和讨论。
