摘　　要：目的探讨高频超声对神经脂肪纤维瘤的诊断价值。方法回顾性分析我院经病理确诊的8例神经脂肪纤维瘤的高频超声表现,观察病变位置、数目、大小、边界、内部回声、血流丰富程度,以及其与周围血管、神经的位置关系等。结果8例神经脂肪纤维瘤均表现为病变神经区域明显增粗,呈膨胀性生长,血流信号不丰富,与周围血管分界清晰。其中6例可探及内部粗细不等低回声神经束被无包膜高回声脂肪包绕,横切面呈“藕片状”改变,纵切面呈“蛇纹状”改变;2例为高回声结节样病灶,无特异性声像图表现。结论神经脂肪纤维瘤的声像图表现具有一定特征性,超声可作为本病首选的诊断方法。Objective To explore the value of high frequency ultrasound in the diagnosis of neurolipofibroma.Methods The high-frequency ultrasound manifestations of 8 cases of neurolipofibroma diagnosed by pathology in our hospital were retrospectively analyze,the lesion location,number,size,boundary,internal echo,blood flow richness,and the position relationship with peripheral blood vessels and nerves were observed.Results All 8 cases of neurolipofibromas showed a significantly thickened and expansive growth of the affected nerve area,with poor blood flow signal and clear boundary from peripheral blood vessels.The hypoechoic nerve bundles with unequal thickness were surrounded by unenveloped hyperechoic fat in 6 cases,which showed“lotus root slices shape”change in transverse section and“serpentine shape”change in longitudinal section.The hyperechoic nodular lesions with no specific sonographic findings in 2 cases.Conclusion The ultrasonographic features of neurolipofibroma has certain characteristics and ultrasound can be used as the first choice for diagnosis.
