Aberrant accessory muscles are rare entities in the hand. The extensor digitorum brevis manus (EDBM) muscle is amongst them and may be seen in association with dorsal ganglion cysts. Distinguishing an EDBM muscle is relevant in the diagnostic consideration of a dorsal ganglion in order to facilitate and guide its proper treatment. To date, there have been only few reports of an EDBM in association with a dorsal ganglion cyst. We report our experience with an incidental intraoperative finding of an intramuscular EDBM dorsal ganglion cyst and follow with a literature review and guide to management.
手部异常副肌是罕见的情况。指短伸肌（EDBM）就是其中之一，可能与背侧腱鞘囊肿同时出现。在背侧腱鞘囊肿的诊断过程中，鉴别EDBM肌肉有助于并指导其恰当治疗。迄今为止，仅有少数关于EDBM与背侧腱鞘囊肿相关的报道。我们报告术中偶然发现的肌内EDBM背侧腱鞘囊肿的经验，并进行文献综述及治疗指导。
