OBJECTIVES
To determine the prevalence and demographic data regarding incidentally encountered elastofibroma dorsi (EFD) in the Saudi population-based on chest CT (computed tomography) scans.
METHODS
This retrospective study was carried out on 4,435 chest CT examinations that were collected between January 2014 and December 2016 in Riyadh, Saudi Arabia. One musculoskeletal radiologist who was unaware of the patients' clinical presentations or reasons for CT study reviewed the 4,435 chest CTs prospectively, searching for soft tissue tumors in the subscapular region.
RESULTS
Elastofibroma dorsi was incidentally confirmed via CT scan in 36 of the 4,435 patients, including 8 males and 28 females, with a mean age of 76.6 years, yielding a prevalence of 0.8%. Elastofibroma dorsi was more common in females, with a 3.3-fold higher prevalence (77.8%) as compared to males (22.2%); however, this difference was not statistically significant (>0.05). Twenty-five (69.44%) patients had unilateral EFD and 11 (30.56%) had bilateral EFD. Right-sided EFD was encountered in 60% of females and 50% of males. Furthermore, there was no statistically significant correlation between the size of EFD and the patient's gender or age (>0.05).
CONCLUSION
Elastofibroma dorsi is a rare but uncommon incidental finding on routine chest CT examination encountered in 0.8% of elderly Saudi patients.
目的
基于沙特人群的胸部 CT（计算机断层扫描）检查，确定偶发性背阔肌弹性纤维瘤（EFD）的患病率和人口统计学数据。
方法
本回顾性研究对 2014 年 1 月至 2016 年 12 月在沙特阿拉伯利雅得收集的 4435 例胸部 CT 检查进行了研究。一名肌肉骨骼放射科医生在不知道患者临床表现或 CT 检查原因的情况下，前瞻性地对 4435 例胸部 CT 进行了检查，以寻找肩胛下区域的软组织肿瘤。
结果
36 例 4435 例患者经 CT 扫描偶然证实患有背阔肌弹性纤维瘤，其中男性 8 例，女性 28 例，平均年龄 76.6 岁，患病率为 0.8%。女性中背阔肌弹性纤维瘤更为常见，患病率为 77.8%，男性为 22.2%，患病率高 3.3 倍，但差异无统计学意义（>0.05）。25 例（69.44%）患者单侧 EFD，11 例（30.56%）双侧 EFD。右侧 EFD 在女性中占 60%，男性中占 50%。此外，EFD 大小与患者性别或年龄之间无统计学显著相关性（>0.05）。
结论
背阔肌弹性纤维瘤是一种罕见但不常见的偶发性发现，在 0.8%的老年沙特患者常规胸部 CT 检查中发现。
