CT诊断肩背部弹力纤维瘤14例

CT Diagnosis of Elastofibroma Dorsi

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 .
