摘要
目的探讨结节性筋膜炎的病理、临床特点和MRI影像征象。方法回顾外科手术和病理证实35例结节性筋膜炎,最终23例MRI图像。图像特征包括位置,大小,信号特征,强化方式,筋膜尾征。计算筋膜尾征在结节性筋膜炎诊断的敏感度、特异度,与结节性筋膜炎的相关性。结果 23结节性筋膜炎单发实性结节或肿块,最常见位于上肢,83%病变范围小于4cm,MRI影像表现为T_1WI呈等信号,T_2WI呈高信号,增强后明显强化。19例出现筋膜尾征,筋膜尾征对结节性筋膜炎诊断的敏感度为83.8%,特异度为79.5%,筋膜尾征与结节性筋膜炎显著相关性(r=0.714)。结论结节性筋膜炎相对特异的临床表现,MRI影像征象中筋膜尾征良好的诊断效能,可以对部分结节性筋膜炎做出影像学诊断,有利于临床治疗方案的制订。
Objective To explore the imaging characteristics of nodular fasciitis and the diagnosis efficiency of fascia tail sign at MR images in the nodular fasciitis. Methods The clinical datas and MRI imaging signs of nodular fasciitis pathology confirmed in 23 cases were retrospectively analyzed. Image features include the position,size,signal characteristics,enhancement pattern,and fascia tail sign. Sensitivity and specificity of fascia tail sign were calculated in the diagnosis of nodular fasciitis. The association between the presence of fascia tail sign and nodular fasciitis was analyzed. Results 23 cases of nodular fasciitis were a single solid nodules or masses. The most common was located in the upper limbs. most lesions was less than 4cm. MRI image showed T_1WI was the same signal,T_2WI was high signal,and enhanced T_1WI displayed significantly enhanced. Fascia tail sign was present in 19 cases,with sensitivity of 83.8%,specificity of 79.5%. Fascia tail sign and nodular fasciitis have significant correlation（r =0.714）.Conclusion The clinical features and imaging performance of nodular fasciitis,especially significantly diagnostic performance of the fascia tail sign,can be made on the part imaging diagnosis of nodular fasciitis.
