目的观察MRI表现与病理诊断在手足局限型腱鞘巨细胞瘤中的应用,评价二者临床诊断效果。方法对该院2014年4月—2017年3月收治的33例手足局限型腱鞘巨细胞瘤患者临床资料进行回顾性分析,均给予患者磁共振成像(MRI),随后均给予病理与手术确诊,观察两组检测方式诊断情况。结果对该组患者诊断后各数据统计显示,经MRI显示肿瘤表现“分叶状”9例,“结节状”21例,不规则3例;边界表现不清者4例,边界清晰者29例;T1WI表现等信号31例,均匀低信号8例,低混杂信号4例;T2WI表现高低混杂信号25例,高信号3例,不均匀低信号5例。结论 MRI表现应用于受阻局限型腱鞘巨细胞瘤中的诊断中具有较高准确率与特异性,在诊断受阻局限型腱鞘巨细胞瘤中具有独特优势,效果显著。
Objective To observe the application of MRI and pathology in the detection of giant cell tumor of the tendon sheath of the hand and foot, and to evaluate the clinical diagnosis. Methods The clinical data of 33 patients with limited-type giant cell tumor of the tendon sheath treated in our hospital from April 2014 to March 2017 were retrospectively analyzed. All patients were given MRI, and subsequently confirmed by pathology and surgery. Observe the diagnostic methods of the two groups. Results The data of all the patients after diagnosis showed that there were 9 cases with “lobulated” tumor, 21 cases with “nodular”, 3 cases with irregularity, 4 cases with unclear border, There were 29 cases with clear boundary, 31 cases showed T1WI signal, 8 cases had low uniform signal and 4 cases showed low mixed signal. 25 cases showed high and low mixed signals on T2WI, 3 cases showed high signal and 5 cases showed non-uniform low signal. Conclusion The MRI findings have high accuracy and specificity in the diagnosis of limited giant cell tumor of tendon sheath. It has unique advantages in the diagnosis of limited giant cell tumor of tendon sheath, and the effect is obvious.
