摘　　要：目的 总结腱鞘纤维瘤的临床表现特点,探讨其影像学表现特征,以提高影像诊断水平。方法 回顾性分析8例经手术病理证实的FTS的临床和影像学资料,总结其X线平片、CT、MRI表现特点。结果 8例FTS均位于四肢小关节,手部3例,足部5例,其中位于关节背侧5例。病灶最大径0.6～3.5cm,平均2.5cm。所有病灶为单发软组织密度信号肿块,X线平片、CT平扫病灶密度与肌肉相仿,周边呈略高密度,部分病灶内见钙化,可压迫或侵蚀邻近骨质;在MR T1WI呈等信号,在T2WI上呈低、等或高信号,DWI上呈高信号。结论 结合CT及MRI能为诊断FTS提供有价值的信息。Objective To study the X-ray, CT and MR imaging features of fibroma of the tendon sheath （FTS）. Methods X-ray, CT and MRI findings of surgically and pathologically proved FTS in 8 patients were retrospectively analyzed. Results 3 and 5 FTS were located in the upper and lower extremities respectively, and 5 of them on the flexor surfaces. The tumor sizes varied from 0. 6 to 3.5 cm in the largest diameter, with mean of 2.5 cm. All lemons appeared as a discrete soft tissue mass on imaging. The leisions＇ density was similar to tousle, and resulted in scalloping or erosion of the adjacent hone. MR imaging manifested as isointense lesion on Tl WI and hypo-, iso- or hyperintense compared with muscle on T2 WI, and hyperintense signal intensity on DWI. Conclusion X-ray, CT and MRI can provide helpful information for the diagnosis of FTS. DWI can describe the feature of FTS in a special way.
