儿童髋关节一过性滑膜炎的MRI表现

MRI diagnosis of transient synovitis of the hip in children

目的：探讨儿童一过性髋关节滑膜炎的磁共振诊断价值。方法分析23例儿童一过性髋关节滑膜炎的磁共振影像资料，所有患儿行横断位T2 WI＋FS、T1 WI ，冠状位用 T2 WI＋ FS、T1 WI ，采用常规自旋及快速自旋回波序列。结果23例患儿共28侧髋关节发病，18例为单侧发病，5例为双侧，所有病变髋关节不同程度关节积液，T 2 W I上表现为关节腔内片状、带状高信号影，T1 WI上呈低信号，6侧关节滑膜增厚，4侧关节周围软组织肿胀，所有患侧股骨头骨骺、干骺端及髋臼骨质正常。6例治疗2～5周后复查，基本恢复正常。结论磁共振对儿童一过性髋关节滑膜炎的诊断安全、可靠，在诊断与鉴别诊断上具有很高的价值。

Objective To evaluate the value of MRI in transient synovitis of the hip in children .Methods Magnetic res‐onance imaging data of 23 cases of transient synovitis of the hip in children were analyzed retrospectively .All children un‐derwent Axial T2 WI ＋ FS ,T1 WI ,coronal T2 WI ＋ FS ,T1 WI ,with conventional spin‐echo sequences and fast spin‐echo sequences .Results In all ,there were 28 hip joints of 23 cases with transient synovitis ,of which 18 cases were unilateral , 5 cases bilateral;all had varying degrees of joint effusion in lesions hip joints .The intra‐articular effusion had a plaque‐like or ribbon shape high signal on T2 WI ,and low signal on T1 WI .6 hip joint’s membrana synovialis thickened ,4 hip joint soft tissues swelled .All of the femoral epiphysis ,metaphysis and acetabular bone of sick hip were normal .6 cases re‐checked after treatment for 2～5 weeks ,and all returned to normal .Conclusion MRI has a high value in the diagnosis and differential diagnosis of transient synovitis of the hip in children .The diagnosis is reliable and safety .
