目的分析结节性筋膜炎(NF)的CT及MRI表现,以提高影像诊断水平.方法回顾性分析经手术病理证实的9例NF的影像表现,其中4例行CT检查,5例行MR检查.结果 9例NF中,5例位于下肢,2例位于腹壁,2例位于外耳道.病灶最大直径为1.1～9.5 cm,平均(3.7±0.3)cm.所有病灶均表现为单发实性软组织肿块,CT平扫显示肿块密度与肌肉密度相仿;病灶在MR T_1WI呈等低信号,在T_2WI呈混杂高信号,增强扫描肿块呈均匀或不均匀中、重度强化.结论 CT及MR检查能为临床诊断及鉴别诊断NF提供有价值的信息.

Objective To explore the CT and MR imaging features of nodular fasciitis(NF), which will in return improve the standard and quality of diagnosis. Methods CT (n = 4) and MRI (n = 5) findings of pathologically proved nodular fasciitis in 9 patients were retrospectively analyzed. Results Of 9 NF, 5 were located in the lower extremities, 2 in the abdominal wall, and the others in the acoustic duct. The resected tumor size vary from 1.1 to 9. 5 cm in the largest diameter and mean (3.7±0.3) cm. All lesions appeared as a discrete solid mass on imaging. The CT value of lesions was similar to muscle. MR imaging manifested as a hypo to isointense lesion on T_1WI and hyperintense signal intensity on T_2WI. There was homogeneous or heterogeneous moderate to significant enhancement in the lesions. Conclusion CT and MRI can provide helpful information for the clinical and differential diagnosis of NF.
