MRI诊断布鲁氏菌性髋关节炎

MRI in diagnosis of brucellosis arthritis in the hip

目的分析布鲁氏菌性髋关节炎(BAH)MRI特征。方法回顾性分析100例BAH患者临床及MRI资料,依据临床病史描述症状持续时间及发病部位进行分期与分型。结果100例BAH中,男84例,女16例;单侧关节受累61例,双侧关节受累39例。MRI表现以急性期及全关节型最多见;30例双侧BAH的MRI表现基本一致,9例不一致。伴随布鲁氏菌病抗体滴度成倍增加,BAH病变无明显成比例进展趋势;MRI可清楚显示BAH治疗后转归。结论BAH男性常见,以单侧关节发病为主,全关节型常见;MR检查对早期诊断BAH具有优势。

Objective To observe MRI features of brucellosis arthritis of the hip(BAH).Methods Clinic and MRI data of 100 patients with BAH were retrospectively analyzed,and BAH were staged and typed based on the duration of symptoms and the location of disease.Results Among 100 BAH patients,84 were males,16 were females.Unilateral joint involvement was found in 61 cases,while bilateral joint involvements in 39 cases.The most common MRI findings of BAH were acute phase and total joint type.MRI findings of bilateral BAH were consistent in 30 cases and inconsistent in 9 cases.There was no obvious proportional progress in BAH lesions with increasing of serum agglutination test.MRI could clearly show the changes after BAH treatment.Conclusion BAH infection is common in males,mainly involving unilateral joint,and total joint type is common.MR examination has advantages in early diagnosis of BAH.
