A myxoid cyst on the dorsum of the left index finger is presented. A connection of this pseudocyst to the underlying joint was shown by means of magnetic resonance imaging. Surgically the connecting tract to the distal interphalangeal joint was easily demonstrated and histologically a ductal structure was focally seen by means of serial sections. These structures also suggest such a connection. These findings confirm the view that this pseudocyst can be interpreted as a ganglion. Therapeutically complete excision with careful tying off of the channel to the joint appears to be the best method to avoid recurrence. The injection of sclerosing agents, a conservative treatment modality proposed by some authors, may be problematic in the light of the pathogenesis discussed here; however damage to the finger joint has not been so far observed.
本文报道了一例发生于左手食指背侧的黏液样囊肿。磁共振成像显示该假性囊肿与下方关节相连。手术中很容易发现通向远侧指间关节的连接管道，组织学检查通过连续切片在局部可见导管结构。这些结构也提示了这种连接。这些发现证实了这种假性囊肿可被解释为腱鞘囊肿的观点。治疗上，完整切除并仔细结扎通向关节的管道似乎是避免复发的最佳方法。一些作者提出的硬化剂注射这种保守治疗方式，鉴于本文讨论的发病机制可能存在问题；然而，迄今为止尚未观察到对指关节的损害。
