髂胫束摩擦综合征的MR表现及临床价值
MR manifestations and clinical significance of iliotibial band friction syndrome
目的 描述髂胫束摩擦综合征的MRI表现,提高对本病的认识及诊断.方法 回顾性分析2011年1月至2012年8月北京中日友好医院16例共18个诊断为髂胫束摩擦综合征的膝关节的MR表现特征.结果 髂胫束摩擦综合征的MRI表现包括:(1)股骨外侧髁侧方、近侧或远侧的境界不清的异常信号;(2)髂胫束表面或深部的异常信号;(3)髂胫束与股骨外侧髁之间局限性积液;(4)髂胫束位于股骨外髁水平的部分增厚;(5)关节腔积液;(6)其他异常.结论 MRI是诊断髂胫束摩擦综合征的较好方法.
更多Objective To describe the MRI features of Iliotibial band friction syndrome (ITBFS),in order to improve the understanding and diagnosis of ITBFS.Methods The MR findings of 16 patients (18 knees) of clinically diagnosis ITBFS were reviewed retrospectively.Results The MRI features of ITBFS:(1)Ill-defined abnormal signal intensty extended to the lateral femoral epicondyle.(2) Poorly defined abnormal signal intensity presented deep to the ITB adjacent to the lateral femoral epicondyle.(3)Fluid collections medial to the ITB adjacent to thelateral femoral epicondyle.(4)The part of ITB over the lateral femoral epicondyle was thicker.(5)Joint effusion.(6)Other abnormal signs.Conclusion MRI is a relatively good method for detection of ITBFS.
