摘要:
目的:探讨膝关节痛风性关节炎(GA)的MRI表现。方法:收集结合双能量CT确诊的14例GA患者的资料并分析其MRI表现,进行回顾性研究。结果:14例膝关节GA患者中,双能量CT显示尿酸结晶主要沉积于肌腱、韧带、滑膜以及关节软骨面,其中沉积于股四头肌肌腱6例,髌韧带4例,前后交叉韧带2例,其余2例主要累及膝关节周围滑膜;MRI显示痛风石在T1WI上显示同肌肉等信号,在PDWI上信号可以多样化,以混杂等信号至混杂高信号为主。结论:膝关节GA患者的发病位置及MRI信号特点具有一定的特征性,MRI有利于显示痛风结晶及早期表现。

Abstract: Objective To explore MRI?indings of gouty arthritis?GA) of?nee joint. Methods A retrospective study was conducted on 14 patients with GA of knee joint diagnosed with dual-energy CT, and their MRI findings were analyzed. Results In 14 patients with GA of knee joint, dual-energy CT showed that uric acid crystals were mainly deposited in tendons, ligaments, synovium and articular cartilage, including 6 cases in quadriceps tendon, 4 cases in patellar ligament, 2 cases in anterior and posterior cruciate ligaments, and the remaining 2 cases mainly involved the synovium around the knee joint. MRI showed that the signals of the tophi were similar to those of muscles on T1WI, while the signals on PDWI was diversified, mainly ranging from heterogeneous isointensity to heterogeneous hyperintensity. Conclusion The location and MRI signal characteristics of knee GA patients are specific, and MRI is conducive to display gout crystallization and early manifestations.
