摘　　要：目的探讨背部弹力纤维瘤的CT和MRI表现特点,提高影像诊断水平。方法回顾性分析8例背部弹力纤维瘤的临床影像学资料,并结合文献分析。本组患者均无明显临床症状,男4例,女4例,年龄30～68岁。包括CT检查4例,MRI检查8例,总结临床影像学表现特点。结果 8例背部弹力纤维瘤发生于左侧3例、右侧3例和双侧2例,肿瘤均位于肩胛下区,呈扁平椭圆形贴于胸壁,在CT和MRI上表现为肌肉样密度(信号)的软组织肿块,内散在分布条片状脂肪样密度(信号)灶,增强扫描肿块轻度不均匀强化。结论背部弹力纤维瘤的CT和MRI表现具有诊断特征性,不难做出术前正确诊断。Objective To study CT and MRI appearance of elastofibroma dorsi in correlation with pathology. Methods The clinical features （8 patients）, CT （4） and MR （8） imaging findings of elastofibroma dorsi were retrospectively analyzed. Results In 8 asymptomatic patients （4 men and 4 women, age range： 30-68 years）, the oval soft tissue tumors were located in the left （3）, right （3）, or bilateral （2） subscapular regions. The CT densities and MR signal intensities of the masses were similar to those of muscle with some interlaced fat-like areas within the lesions. The masses enhanced slightly and heterogeneously with intravenous contrast medium. Conclusion Characteristic CT and MRI features of elastofibroma dorsi enable correct preoperative diagnosis.
