Abstract:
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.
