| 目的 观察背部弹力纤维瘤（EFD）的18F-FDG PET/CT表现。方法 回顾性分析26例EFD患者的18F-FDG PET/CT资料，比较男性与女性患者、年龄<72岁与≥72岁患者、体积<39 cm3与≥39 cm3病灶之间18F-FDG最大标准摄取值（SUVmax）及SUVmax与肝脏血池平均标准化摄取值比值（SUR-BP）的差异。结果 26例患者中，19例EFD累及双侧，7例累及单侧（均为右侧）；共45个EFD病灶，表现为位于肩胛下角内侧与后胸壁间被肩胛下肌、背阔肌、前锯肌、菱形肌包围区域的类圆形或梭形软组织肿物，密度接近或略低于周围正常肌肉组织，病灶放射性摄取较周围肌肉组织呈轻至中度增高。39个EFD病灶的18F-FDG摄取低于肝脏血池本底，6个病灶的18F-FDG摄取高于肝脏血池本底。不同性别、年龄患者间及不同体积病灶间SUVmax、SUR-BP差异均无统计学意义（P均>0.05）。结论 EFD的PET/CT表现具有一定特异性，有助于诊断。 |

| Objective To observe 18F-FDG PET/CT manifestations of elastofibroma dorsal (EFD). Methods 18F-FDG PET/CT findings of 26 patients with EFD were retrospectively analyzed. The differences of maximum standard uptake (SUVmax) of lesions and the ratio of SUVmax to mean standardized uptake of liver (SUR-BP) were compared between males and females, patients aged <72 years and ≥ 72 years, lesion volume <39 cm3 and ≥ 39 cm3, respectively. Results Among 26 patients, there were 19 patients of bilateral EFD involvement and 7 of unilateral involvement (right lateral).There were total 45 EFD lesions in all 26 patients. All the lesions were found as round or fusiform soft tissue masses,located between inferior corner of scapula and posterior chest wall, bordered by the subscapularis, rhomboid, latissimus dorsi and serratus anterior muscles. The density of lesions were close to or slightly lower than that of the surrounding normal muscle tissue. Radioactive uptake of lesions increased slightly to moderately compared with the surrounding normal muscle tissue. Except for 6 lesions with higher 18F-FDG uptakes, the uptakes of 18F-FDG in the other 39 EFD lesions were lower compared with the hepatic blood pool. There was no significant difference of SUVmax nor SUR-BP among EFD patients with different sex, age norlesion volume (all P>0.05). Conclusion 18F-FDG PET/CT manifestations of EFD demonstrate some characteristics, and might be helpful to diagnosis of this disease. |
