摘要
目的通过分析布鲁氏菌性骶髂关节炎(BSI) MRI表现,提高对其的认识。方法搜集68例BSI患者行MRI扫描,序列包括T1WI,T2WI及短时间反转恢复(STIR),5例行T1WI增强扫描,由两位高年资影像诊断医师分别对搜集的68例临床明确诊断BSI的MRI图像进行分析,包括确定累及关节(单侧/双侧)、T2WI关节软骨信号(增高/降低)、STIR序列骨髓信号增高、脂肪沉积、周围软组织水肿信号及脓肿形成。结果本组BSI单侧关节受累51例,占75%;双侧关节受累17例,占25%。早期BSI MRI T2WI和STIR序列显示关节软骨及骨髓信号增高,周围软组织炎性水肿并少数脓肿形成,增强后早期病变关节以均匀强化为著,周围脓肿呈环形强化;慢性期表现为关节软骨破坏,信号减低,部分脂肪沉积。结论 BSI男性感染更为常见,多发生在较年轻群体;以单侧关节发病为主;MRI检查对诊断早期BSI具有优势。
Objective To enhance the understanding of Sacroiliitis in Brucellosis(BSI)by evaluating MRI images.Methods Two senior radiologists analyzed the MRI images of 68 confirmed BSI cases,including affected joints(single side/both sides),T2WI articular cartilage signals(increased/reduced),STIR series marrow signals,lipid deposition,peripheral soft tissue edema signals and abscess formation.Results 51 cases of unilateral joints and 17 cases of bilateral joints with BSI were recorded,with constituent ratio of 75%and 25%respectively.Among the unilateral-joint cases,the constituent ratio of right-sided cases(58.9%)is slightly higher than the left-sided cases(41.1%).The MRI images of early-stage BSI on T2WI and STIR series showed hyperintense signals,and inflammatory edema of peripheral soft tissue and abscess was formed.Lesions enhanced uniformly,while the abscess had rim enhancement.The chronic stage showed articular cartilage destruction,reduced signals in T2 WI,and partial lipid deposition.Conclusion Presence of BSI in male patients is common,most of which occurred in younger age group.The cases of BSI more often concentrate on unilateral joints.MRI examination has advantages in diagnosis of BSI at an early stage.
