摘　　要：目的探讨髋关节结核的CT、MRI表现及其临床应用意义。方法回顾性分析经手术病理证实的31例髋关节结核的CT、MRI影像资料。结果髋关节结核的主要CT、MRI表现为:(1)病灶多为单发;(2)骨性关节面破坏,可有硬化边;(3)关节周围软组织肿胀、脓肿及钙化;(4)关节间隙变宽或变窄,关节腔积液;(5)关节邻近骨质疏松;(6)关节脱臼等。MRI对病灶及范围显示更佳,病灶一般T1WI为等低信号,T2WI为等高信号,压脂为高信号,增强见强化。结论髋关节结核CT表现结合临床一般能够诊断,MRI对术前显示病变范围必不可少。Objective To explore the value of CT and MRI in the diagnosis of tuberculosis of hip joint. Methods Imaging data of 31 cases with tuberculosis of hip joint confirmed by pathology and surgery were analyzed retrospectively. Results The CT and MRI features of tuberculosis of hip joint included：（1）only one side of hip joints suffered from tuberculosis of hip joint in all of the 31 cases;（2）demolished bone articular surface ,slight sclerosis-bordered focus;（3）soft tissue swelling and abscess and calcify; （4）widened or narrowed joint space,the articular cavity accumulated the liquid;（5）closs by bone soft ofjoint;（6）the joint dislocates etc. The MRI shows to the focus and scope better, in order to equal the signal, the general T1WI of focus is in order to equal the high signal,the T2WI press the fat as high signal, strengthening to see enhance. Conclusion The tuberclosis of hip joint can be examined generally with CT, combing the clinic data. The MRI is essential to show the pathological changes scope before operation.
