MRI diagnosis of bone marrow edema syndrome of the hip
-
摘要:
目的探讨髋部骨髓综合征的影像学诊断。 方法收集我院经临床、MRI及X线3~6个月随访证实13例髋部骨髓水肿综合征的影像学资料，进行回顾性分析，其中男性9例，女性4例，13例MRI检查，5例X线检查。 结果13例髋部骨髓水肿综合征中，右髋8例，左髋5例；病变累及股骨头、股骨颈10例；累及股骨头、股骨颈及股骨粗隆3例；MRI表现：T1WI低信号13例；T2WI稍高信号或高信号12例，等信号1例；13例STIR或PDW-SPAIR均为高信号；4例关节腔少量积液，呈长T1、长T2信号；X线表现：5例股骨头、股骨颈及股骨粗隆骨质密度减低；所有病例骨皮质和股骨头外形完整，周围软组织结构正常。 结论熟悉并掌握髋部骨髓综合征的影像学特点，有利于做出正确诊断。 Abstract:ObjectiveTo investigate the imaging diagnosis of bone marrow edema syndrome of the hip. MethodsThe imaging data of 13 cases (9 males and 4 females) of bone marrow edema syndrome were collected. All patients were followed-up for 3 to 6 months.13 patients underwent MRI scanning and 5 patients underwent X-ray examination. ResultsThirteen cases of bone marrow edema syndrome of the hip, right hip in 8 cases, left hip in 5 cases. The bone marrow edema pattern involved the femoral head and femoral neck in 10 hips. The bone marrow edema involved thefemoral head and femoral neck and femoral trochanteric in 3 cases. The MRimages demonstrated low signal intensity in all 13 cases on T1WI and normal signal intensityin 1 case on T2WI.moderateor high signal intensity in 12 cases on T2WI and high signal on T2 fat suppressed in all 13 cases. A small joint effusion was observed in 4 cases on T2WI. X-ray manifestations: femoral head and femoral neck bone density decrease in 5 cases. The femoral head shape and bone cortex were normal in all 13 cases. ConclusionFamiliar with the imaging findings of bone marrow edema syndrome of the hip canimprove the correct diagnosis. -

男,44 岁,左髋骨髓水肿综合征. A: 冠状T1WI 示左侧股骨头、颈低信号; B: 冠状T2WI 示左侧股骨头、颈稍高信号; C: 冠状位STIR序列示左侧股骨头、颈高信号,信号均匀,边界清楚,关节腔少量积液; D: 3 个月后MRI复查: 冠状位STIR 示左侧股骨头颈信号正常,关节腔少量积液已吸收.

男,43 岁. A: 冠状位STIR 序列示左侧股骨头、股骨颈及股骨粗隆间高信号,关节腔少量积液; B: 3 个月后MRI复查: 冠状位STIR示左侧股骨颈见小片状高信号残余,股骨头、 股骨颈及股骨粗隆间大部分高信号消失,关节腔少量积液吸收.
