结节性筋膜炎的MRI表现

MR Imaging of Nodular Fasciitis

目的分析结节性筋膜炎(NF)的MRI表现,以提高影像诊断水平。材料与方法:回顾性分析经手术病理证实的6例NF的MRI表现。结果:6例NF中,3例位于上肢,2例位于面颊部,1例位于下肢。所有病灶均表现为单发实性软组织肿块,T_1WI呈等或低信号,在T_2WI呈稍高或高信号,增强扫描肿块呈均匀或不均匀强化。结论:MRI检查能为临床诊断及鉴别诊断NF提供有价值的信息。

Purpose： To explore the MR imaging features of nodular fasciitis （ NF）, which will in return improve the standard and quality of diagnosis. Materials and Methods findings of pathologically proved nodular fasciitis in 6 patients were retrospectively analyzed. Results Of 6 NF, 4 were located in the upper extremities, 2 in the cheek, and the others in the lower extremities. All lesions appeared as a discrete solid mass on imaging. T1 WI showed isointense mass, T2 WI showed isointense and hyperintense mass, contrast images showed heterogeneous or homogeneous enhancement. Conclusions MRI Can provide helpful information for the clinical and differential diagnosis of NF.
