摘　　要：目的:探讨大转子疼痛综合征(GTPS)患者的MRI表现。方法:回顾性分析2018年1月-2020年4月在本院经临床诊断为GTPS的20例患者的临床及MRI资料。MRI扫描序列主要有冠状面和横轴面T_(1)WI、T_(2)WI和STIR序列。结果:20例患者累及26髋。主要MRI表现:臀中肌或臀小肌肌腱增厚或信号增高(n=9);臀中肌或臀小肌肌腱纤维局灶性缺失(n=16);臀中肌或臀小肌肌肉萎缩、脂肪浸润、肌肉肌腱钙化(n=1)。多伴有周围软组织水肿(n=26)和转子区滑囊扩张、积液(n=26),可伴有肌肉肌腱“羽翼状”水肿信号(n=4)及股骨大转子骨髓水肿(n=8)。结论:MRI可较为直观显示GTPS的影像学特征,为临床干预提供客观依据。Objective:To investigate the MRI features of the greater trochanteric pain syndrome(GTPS).Methods:The clinical and MRI data of 20 patients with GTPS in our hospital from January 2018 to April 2020 were analyzed retrospectively.The main MRI sequences included coronary and axial T_(1)WI,T_(2)WI and short time inversion recovery(STIR).Results:26 hips were involved in 20 patients.The main MRI features were as follows:thickened or increased hyperintensity of the gluteus medius or minimus(n=9);focal loss of tendon fibers(n=16);muscle atrophy and fatty infiltration or hypointense calcium deposit in the musculature(n=1);surrounding soft tissue edema(n=26),bursitis swelling and effusion in the trochanteric area(n=26);"wing-like"edema signal of the gluteus medius or minimus partly(n=4)and bone marrow edema in the greater trochanter(n=8).Conclusion:MRI can directly display the imaging features of GTPS and provide objective evidence for clinical diagnosis and treatment.
