OBJECTIVE
To evaluate magnetic resonance imaging (MRI) features of tubercular involvement of elbow joint.
METHODS
Fourteen patients with tubercular arthritis of elbow were evaluated. The following findings were recorded on MRI (n=12): bones involved; erosions, intraosseous abscesses, synovial thickening, and effusion; hypointensity within the thickened synovium on T2-weighted images; and periarticular soft tissue changes.
RESULTS
The common abnormalities on MRI were synovial thickening and bone erosions (n=12), soft tissue (n=9)/intraosseous (n=5) abscesses, and T2 hypointensity within the thickened synovium (n=5).
CONCLUSIONS
A diagnosis of elbow tuberculosis should be considered if there is a combination of findings involving bone and soft tissue.
目的
评估肘关节结核的磁共振成像（MRI）特征。
方法
对14例肘关节结核性关节炎患者进行评估。在MRI上记录以下表现（n = 12）：受累骨骼；骨质侵蚀、骨内脓肿、滑膜增厚及积液；T2加权图像上增厚滑膜内的低信号；以及关节周围软组织改变。
结果
MRI上常见的异常表现为滑膜增厚和骨质侵蚀（n = 12）、软组织（n = 9）/骨内（n = 5）脓肿以及增厚滑膜内的T2低信号（n = 5）。
结论
如果存在涉及骨骼和软组织的多种表现，应考虑肘关节结核的诊断。
