摘要

傳統上，肘隧道症候群病灶通常藉由神經傳導檢查來定位其病灶，但是由腱鞘囊腫引起的肘隧道症候群，其結果在臨床上並不令人滿意，因為大部分由腱鞘囊腫引起的肘隧道症候群都是在手術中發現的，而非在手術前有正確的診斷，雖然CT或MRI在診斷腱鞘囊腫是一個不錯的選擇，但是兩者的不便性和價格昂貴是很大的缺點。我們認為超音波用來診斷由腱鞘囊腫引起的肘隧道症候群是一個很好的工具，不只可以正確的診斷腱鞘囊腫，也可以藉此了解周邊的組織構造，和CT或MRI相比，超音波不止有相同的結果，而且相對的更便利及更便宜。

Lesions of cubital tunnel syndrome are usually localized by performing routine nerve conduction study. However, the results of this study are unsatisfactory when a ganglion is the cause. Therefore, most cases of cubital tunnel syndrome due to a ganglion are diagnosed during surgery and rarely with preoperative imaging study. Computed tomography or magnetic resonance imaging may be the imaging studies of choice for this diagnosis. However, these tools are not always used because of their unavailability and cost. Sonography is a good tool for detecting ganglia and should be considered the initial imaging method for localizing these lesions. Sonograms can depict the ganglion and demonstrate the anatomy of the related cubital tunnel. Sonography appears to be as effective as and less expensive than computed tomography or magnetic resonance imaging. We present two cases that illustrate the usefulness of sonography in evaluating cubital tunnel syndrome due to a ganglion cyst.
