目的：探讨肩背部弹力纤维瘤的CT表现。方法回顾性分析14例接受胸部CT检查并经手术病理证实的EFD患者，其中12例接受CT平扫，2例同时接受CT增强扫描。分析EFD的临床特点及CT表现特征。结果14例患者均为女性，临床表现病灶位于右侧4例、左侧8例、2例累及双侧。CT 共发现16个病灶，呈扁丘状或半圆形肿块，主要呈肌样密度，内见条纹状脂肪密度，增强扫描病灶未见明显强化。结论中老年女性单侧或双侧肩胛下角区无症状性扁丘状肿块，CT 表现为肌样密度伴条纹状脂肪密度无明显强化者，应考虑EFD。应双侧对照，以利于发现体表不易触及的亚临床阶段的病灶。%Objective To explore the CT findings of elastofibroma dorsi (EFD ) .Methods Fourteen pa-tients with EFD confirmed by pathology were collected retrospectively .All patients underwent plain chest CT , while 2 of them underwent contrast enhanced before surgery .clinicalfeatures and CT characteristics of EFD were、all analyzed .Results Fourteen patients were all female .Clinical manifestation shown that lesions were on theright side in 4 patients ,on the left in 8 patients ,and bilateral lesion were detected in 2 patients .Masses were flat mound-like or semi-circular ,mainly were muscular -like density ,and fat density were seen of masses ,pre-senting as spaced stripe .The lesion did not enhance in 2 patients .Conclusions EFD should be considered when unilateral or bilateral subscapular areas asymptomatic masses presenting as muscle -like with striated fatspaced , not enhancing were detected on CT in middle -aged women .Bilateral CT examination is necessary for detecting sub-clinical stage lesions .
