摘要
目的探讨弹力纤维瘤的影像学表现与临床病理特征。方法回顾性分析34例经手术病理证实的弹力纤维瘤患者的影像学及临床病理资料,其中男性2例,女性32例,年龄43~75岁,平均年龄56.7岁。34例患者均行高频超声检查,21例同时行MRI检查。结果 34例共44个肿块,均位于背部肩胛下角区。超声检查44个肿块均呈扁圆形,边界模糊,内呈不均匀中低或高低回声相间排列,42个肿块内未探及血流信号,2个肿块内可探及少许血流信号;MRI检查21例共28个肿块均表现为扁丘状,边界模糊,内呈骨骼肌样低信号,其间夹杂有条纹状的脂肪样高信号,2例(单发者)行增强扫描,1例可见不均匀斑片状强化,另1例未见强化。所有病例病理诊断均为弹力纤维瘤,无包膜,4例内可见大小不等囊腔,镜下肿块内可见大量胶原纤维、弹力纤维及脂肪组织。结论弹力纤维瘤的影像学表现与病理表现基本一致且具有一定特点,结合其特殊发病部位及临床特征,对典型病例可明确诊断。
Objective To analyze the imaging features and pathologic characteristic of elastofibroma dorsi. Methods A total of 34 cases of elastofibroma dorsi confirmed by imaging results and pathology diagnosis were retrospectively enrolled, which included 2 males and 32 females, aged 43-75 years old with mean age of 56.7 years old. All of them underwent high frequency ultrasound examination, meanwhile, 21 cases performed MRI examination. Results Totally 44 masses were found in 34 cases and located in subscapular. All masses were shaped ovally with ill-defined, and appeared alternative hyperechogenic and hypoechogenic without any significant flow by color Doppler sonograms in 42 masses, but a little blood flow signal was detected in 2 masses. Twenty-eight masses in 21 cases were flat mound-like with ill-defined by MRI, which showed skeletal muscle-like low signal mixed with stripes of fat-like high signal. Two of them enderwent contrast enhanced MRI, 1 showed uneven patchy enhancement and 1 was no enhanced. All of the pathology demonstrated elastofibroma dorsi, non-encapsulated,and focal small cystic change was found in 4 cases, the plenty of collagen fibers, elastic fibers and adipose tissue was seen under microscope. Conclusion It is demonstrated that the imaging findings of elastic fibroma are basically consistent with pathological manifestations and showed certain characteristics, which could be diagnosed clearly in typical cases by special pathogenesis and clinical features.
