| 摘 要：［目的］ 分析手足腱鞘巨细胞瘤(giant cell tumors of the tendon sheath，GCTTS)的MRI表现，以提高对其认识和诊断水平。［方法］ 回顾性分析25例经手术病理证实的手足部GCTTS患者的MRI表现特点。［结果］ 25例手足部GCTTS中，局限型20例，弥漫型5例，所有病例均可见软组织肿块紧贴或包绕肌腱生长，其中5例可见邻近骨质侵蚀。病灶信号与正常骨胳肌相比，T1WI上19例呈等信号，4例呈等低信号，2例呈低信号；T2WI上信号表现多样化，9例呈混杂信号，6例呈高信号，4例呈稍高信号，6例呈低信号；12例增强扫描后，9例病灶呈明显不均匀强化，3例呈明显均匀强化。［结论］ 手足GCTTS以局限型多见，MRI上表现有特征性，MRI检查对疾病诊断、治疗方案制定等可提供可靠依据。 |

| Abstract：［Purpose］ To analyze the MRI manifestations of giant cell tumors of tendon sheath (GCTTS) in extremities to improve the diagnostic accuracy. ［Methods］ MRI of 25 cases with GCTTS in extremities pathologically confirmed were reviewed retrospectively. ［Results］ Of the 25 cases，20 cases were localized GCTTS，5 cases were diffused GCTTS. All the lesions showed a mass adjacent to or enveloping a tendon，with the erosion of adjacent bones in 5 cases.On T1WI，the signal intensities of GCTTS were equaled to those of skeletal muscle in 19 cases，mild hypointense in 4 cases，obervious hypointense in 2 cases. On T2WI，the signal intensities of GCTTS were inhomogeneous in 9 cases，obervious hyperintense in 6 cases，mild hyperintense in 4 cases，hypointense in 6 cases. Of the 12 cases with gadolinium-enhanced images，9 cases showed inhomogeneous enhancement，and 3 cases showed homogeneous enhancement. ［Conclusion］ Most cases of the GCTTS in extremities are localized GCTTS，MRI is able to depict the characteristic of GCTTS，which is valuable for diagnosis and treatment. |
