目的：探讨结节性筋膜炎的CT和 MRI表现。方法：回顾性分析10例经病理证实的结节性筋膜炎的CT和MRI表现。结果：10例中4例位于上肢，4例位于下肢，2例位于腹壁。病灶均表现为单发实性软组织肿块（肌内型6例，肌间型2例，皮下型2例），CT平扫示肿块密度稍低于肌肉密度，增强扫描有明显强化。MRI 检查：病灶于T1 WI 呈等或稍低信号，T2 WI呈不均匀高信号，其中1例病灶边缘可见囊变区，3例病灶中央可见低信号，增强扫描肿块呈均匀或不均匀中度-重度强化，边界清。结论：结节性筋膜炎的CT和 MRI表现有一定特征性，两种方法均有助于本病的诊断及鉴别诊断。

Objective:To investigate the imaging features of nodular fasciitis so as to improve the quality of diagnosis. Methods:CT and MRI imaging features of 10 cases with nodular fasciitis confirmed by pathology were analyzed retrospec-tively.Results:Of the 10 cases,all had a single lesion with a soft tissue mass,including intramuscular type 6 cases,muscle clearance type 2 cases,and subcutaneous type 2 cases.As to their locations,4 cases of nodular fasciitis were in the upper limbs,4 cases were in the lower limbs,and 2 cases were in the abdominal wall.The plain CT showed that the density of the lesions was a little bit lower than that of the muscle and significant enhancement appeared after contrast injection.MRI showed a slight hypo-to isointense signal intensity on T1 WI and hyperintense on T2 WI.In one of the cases cystic change could be seen at the edge of the lesion,and in 3 cases low signal could be seen in the center.The lesions showed homoge-neous or heterogeneous moderate to intensive enhancement after contrast inj ection and had clear boundary.Conclusion:There are some characteristic imaging features in nodular fasciitis,all of these imaging findings are helpful in clinical diagno-sis before surgery.
