目的：探讨肌内腱鞘囊肿的M RI影像特征与病理，以提高其M RI诊断准确性。方法分析34例经我院病理证实的肌内腱鞘囊肿的临床和M RI资料。结果均发生于四肢，其中肘部5例、腕部3例、膝部24例、踝部2例，均呈T1低、T2高、T2 FLAIR低信号，T2 STIR呈高信号，DWI表现为不均匀高信号；未累及邻近骨骼与关节。其中10例病灶见边缘“云絮”状或“花边”状水肿信号，19例病灶内见低信号分隔带；钆喷替酸葡胺（Gd‐DT PA ）增强，整个病灶无强化。结论光整无强化的囊样病灶及病灶内均匀一致的窄带状无强化低信号分隔带是肌内腱鞘囊肿的特征性表现。

Objective To discuss the MRI imaging characteristics and pathology of ganglion in muscles and to improve the MRI diagnostic accuracy .Methods The clinical and MRI imaging data of 34 cases with ganglion in muscles confirmed by pathology in our hospital were analyzed .Results All occurred in limb muscles .There were 5 cases in elbows ,3 cases in twists ,24 cases in knees ,and 2 cases in ankles .All of them had T1 low ,T2 high ,T2 FLAIR low signal ,and T2 STAIR showed high signal ,all of which showed the heterogeneous high signal on DWI ,without invading joints and bones .10 ca‐ses showed that lesions had“cloud flocculation” or "lace‐like"edema signal ,and another 19 cases showed separations of low signal ,which had no enhancement in Gd‐DTPA enhance‐ed MRI .Conclusion MRI scanning showed no enhancement in thecystic lesions and no‐enhancement low separations presenting the shape of the uniformity narrow float‐ribbon ,which were the characteristic manifestation of ganglion in muscles .
