目的：探讨结节性筋膜炎高频超声声像图特征性表现，分析超声误诊原因。方法：回顾性分析25例经手术和病理证实的结节性筋膜炎患者术前超声声像图表现，总结其临床表现及高频超声声像图特征。结果：25例结节性筋膜炎高频超声声像图特征性表现为单发圆形、椭圆形及梭形，部分可见浅分叶，均无明显包膜，边界尚清，活动度较好，与周围组织无粘连；21例病灶表现为低回声，部分内部可见中高回声,3例为中等回声，1例为高回声；19例病灶后方回声增强。CDFI：19例病灶内部及周边未探及明显血流信号;4例病灶内部或周边探及点状血流信号;2例病灶可见较丰富血流信号，呈低速高阻型，并且病灶体积相对较大。25例病灶中，14例病灶发生在皮下脂肪层，8例累及皮下筋膜层，3例累及肌肉层。超声诊断皮下异常回声15例，超声误诊10例，其中5例为脂肪瘤、2例血管瘤、1例神经源性肿瘤，1例血肿，1例软组织肿瘤。结论：结节性筋膜炎高频超声表现具有一定特征性，对结节性筋膜炎具有重要的诊断价值。 |

| Abstract Objective To investigate high-frequency ultrasonic images of nodular fasciitis and the reasons of ultrasonic misdiagnosis were analyzed. Methods The preoperative sonographic features of twenty-five patients confirmed as nodular fasciitis by operation and pathology were reviewed and analyzed ,and the clinical symptoms and the features of nodular fasciitis were?summarized by high frequency ultrasound. Results High-frequency ultrasonic images of 25 cases nodular fasciitis showed single occurred round, oval and fusiform shape characteristically, part of which had shallow lobes, clear boundary and better activity, without significant envelope or adhesion with surrounding tissues; 21 lesions showed hypoechoic echoes, partly had internal hypoechoic echoes, 3 had moderate echoes, and 1 had hyperechoic echo; posterior echoes were enhanced in 19 lesions. CDFI: 19 lesions did not have significant blood flow signal in or around it, 4 lesions had punctate blood flow signals in or around it, 2 lesions showed pretty abundant blood flow signals, which were low-speed and high resistance type, and whose volume were large relatively. Among 25 lesions, 14 lesions occurred in the subcutaneous fat layer, 8 cases involved the subcutaneous fascia and 3 involved the muscle. Ultrasound diagnosis showed 15 cases were subcutaneous abnormal echoes, 10 cases were ultrasonic misdiagnosis, including 5 cases of lipoma, 2 cases of hemangiomas, 1 case of neurogenic tumors, 1 case of hematoma, and 1 case of soft tissue tumors.Conclusion high-frequency ultrasonic images of nodular fasciitis has a certain sonographic．The high frequency ultrasound has great diagnostic value for nodular fasciitis. |
