【摘要】：目的:探讨痛风性关节炎的MRI表现及其诊断价值。方法:回顾性分析经临床及病理证实的18例痛风性关节炎患者的MRI资料。结果:18例中单关节发病14例,多关节发病4例,共累及24个关节。其中第一跖趾关节8个,膝关节6个,踝关节5个,髋关节2个,肘关节2个,跗骨间关节1个。磁共振表现:滑膜增生(n=18),关节腔或滑膜囊积液(n=16),关节周围软组织肿胀(n=21),穿凿状或不规则状骨质破坏(n=14),骨髓水肿(n=6),关节间隙狭窄(n=10),关节增生(n=12);14个关节可见痛风结节,其中2个单发,12个多发;共发现痛风结节35个,T1WI呈低信号,T2WI信号强度不同,T2WI上8个病灶呈低信号,17个呈低及稍高混杂信号,10个呈稍高信号,增强后26个病灶呈不均匀强化,以边缘强化为明显,5个强化均匀,4个无强化。结论:痛风性关节炎具有多种MRI表现,MRI有利于显示痛风结节及早期病变,对痛风性关节炎的诊断具有较高的价值。
[Abstract]:Objective: to investigate the MRI manifestations and diagnostic value of gouty arthritis. Methods: the MRI data of 18 patients with gouty arthritis proved clinically and pathologically were retrospectively analyzed. Results of 18 cases, 14 cases were single joint, 4 cases were multiple joint, 24 joints were involved. There were 8 first metatarsophalangeal joints, 6 knee joints, 5 ankle joints, 2 hip joints, 2 elbow joints and 1 intertarsal joint. MRI findings: synovial hyperplasia, synovial cavity or synovial sac effusion, swelling of soft tissue around the joint, destruction of bone in the form of chisel or irregular bone, bone marrow edema, stenosis of the articular space, hyperplasia of the joint, and gout nodule in 14 joints. Among them, 2 cases were single, 12 cases occurred, 35 cases of gout nodule showed hypointensity on T _ 1WI, low signal intensity on T _ 2WI, low and slightly high signal intensity on T _ 2WI, slightly high signal intensity in 10 cases, and inhomogeneous enhancement in 26 lesions on T _ 1WI. The edge enhancement was obvious, 5 were homogeneous and 4 were not. Conclusion: the MRI findings of gouty arthritis are helpful to display gout nodules and early lesions, and have a high value in the diagnosis of gouty arthritis.
