Studies have demonstrated favorable outcomes of arthroscopic decompression for ganglion cyst in the supraspinous fossa; however, little attention has been paid to the difficulty in detecting these cysts during arthroscopy. In this report, we present 2 cases in which ganglion cysts in the supraspinous fossa were undetectable during arthroscopy. The ganglion cysts were not identified in these cases during surgery despite arthroscopic decompression being performed through the area in which the cyst was expected until the suprascapular nerve was entirely exposed. After surgery, magnetic resonance imaging (MRI) confirmed the disappearance of the ganglion cyst and external rotation strength was fully improved, without shoulder pain. We emphasize here that surgeons should be aware of this difficulty when performing arthroscopic decompression of ganglion cysts in the supraspinous fossa.
研究表明，关节镜下对上棘窝腱鞘囊肿进行减压可取得良好效果；然而，在关节镜检查期间，这些囊肿的检测难度却很少受到关注。在本报告中，我们介绍2例关节镜检查时无法检测到上棘窝腱鞘囊肿的病例。尽管通过预期囊肿所在区域进行关节镜减压直至肩胛上神经完全暴露，但在这些病例的手术过程中仍未发现腱鞘囊肿。术后，磁共振成像（MRI）证实腱鞘囊肿消失，外旋力量完全恢复，且无肩部疼痛。我们在此强调，外科医生在对上棘窝腱鞘囊肿进行关节镜减压时应意识到这一困难。
