| 目的 幼年性特发性关节炎的早期诊断更易于治疗及改善预后。回顾性研究幼年性特发性关节炎的膝关节MR表现特征以提高对于幼年性特发性关节炎的诊治水平。方法 分析42例幼年性特发性关节炎患儿的膝关节磁共振表现。患者中女18例、男24例,平均年龄10.5岁(5~16岁)。结果 42例JIA患者的42个膝关节可见不同程度的MR异常改变(100％),主要影像学表现包括滑膜增生及血管翳形成、关节腔渗出积液、骨髓水肿、半月板形态及信号异常改变、关节软骨破坏、腘窝淋巴结肿大等。结论 在幼年性特发性关节炎的膝关节MRI表现中,滑膜增厚、关节腔积液及骨髓水肿较为常见;关节软骨破坏及软骨下骨质侵蚀则较为少见。 |

| Objective Early diagnosis of juvenile idiopathic arthritis (JIA) facilitates earlier more aggressive therapy and could improve outcome. Recognition of the features of JIA on magnetic resonance imaging (MRI) will improve disease detection and expedite treatment. This study aims to highlight the relevant MRI features. Methods Forty-two joints of 42 patients with JIA were included in this study. MRI examinations of the knee joints were performed on 42 children with clinically confirmed JIA. All patients met the International League for Rheumatology (ILAR) diagnostic criteria for JIA. Forty-two patients with JIA included 18 female and 24 male and with a mean age of 10.5 years old (ranged from 5 to 16 year old). Results The results showed that various degrees of abnormal changes were found in MR images of all the knee joints of 42 JIA patients (100%). The major manifestations of MR imaging included synovial hyperplasia and pannus formation, joint effusion, bone marrow oedma, adnormality of signal and shape of meniscus, soft tissue swelling, cartilage destruction,popliteal lymphagogue, et al. Conclusion Synovial hypertrophy and joint effusions are the most frequent MR findings of knees in juvenile idiopathic arthritis;Cartilage and bone erosion are uncommonly findings on MR imaging. |
